1 Handling Unit (HU) Definition A handling unit is a physical unit consisting of packaging materials (load carriers/packing material) and the goods contained on/in it. A handling unit is always a combination of products and packaging materials. All the information contained in the product items, for example, about batches, is retained in the handling units and is always available. Handling units can be nested, and you can create a new handling unit from several other handling units. A handling unit has a unique, scannable identification number that you can construct according to industry standards such as EAN 128 or SSCC.

Fig. 1: Example of a Handling Unit

Structure The object ‘Handling Unit’ contains the following attributes: ● ● ● ● ● ● ● ●

Identification number Dimension Weight Volume Status Products and quantities Packaging material Packaging specification

A handling unit consists of a handling unit header and handling unit items. It receives a unique number that is used for identification purposes.

Handling Unit Header The header data of a handling unit is divided up as follows: ● Weight/Volume/Dimension ● General data ● Storage-Specific Data For more information about the different detailed information, see Packing in the Work Center.

Status The handling unit is connected to general status management. This enables you to document the various physical statuses (such as planned or realized) and other attributes (such as, weighed, loaded, blocked, or posted for GI) for a handling unit. If you want to use your own status, you can store a user schema for the packaging material type.

Handling Unit Item The items of a handling unit can consist of material items, auxiliary packaging materials, or other handling units, which are displayed in an overview. For more information about this overview, see Packing in the Work Center.

!--a11y-->

Packaging Materials Definition Packaging materials are used to enclose or hold together the packaged goods. You can pack the packaged goods into or onto the packaging material. The packaging material can be a load carrier. The most important packaging materials are, for example, crates, boxes, containers, wire baskets, and pallets.

Use For each packaging material that you want to use, you must maintain product master data. The gross weight and the volume that you enter in the product master are particularly important for packing. If you create a handling unit, the master data for the packaging material is automatically adopted, and the gross weight and volume become the tare weight and/or tare volume of the handling unit.

The tare weight and tare volume refer to the gross weight and volume of the packaging material. In the case of a container, for example, this is the tare weight of the unloaded container (the total weight of the container minus any goods and packaging materials packed into it).

Structure If you choose the Global Data view in the product master record, you can maintain the following data in the Packing Data screen section (you access product maintenance from the SAP menu. To do this, choose Extended Warehouse Management ® Master Data ® Product ® Maintain Product ):

Section Basic Data: Packing : · Packing group · Reference product for similarly packable products · Standard HU type

Section Basic Data: Packaging Material : · Packaging material type · Handling unit type

Section Capacities · · · · · · · · · · · ·

Maximum allowed weight Excess weight tolerance for the handling unit Tare weight variable Maximum allowed volume Excess volume tolerance for the handling unit Packaging material is closed packaging Maximum level (by volume) Maximum allowed capacity for the packaging material Excess capacity tolerance for the handling unit Maximum packing length of a packaging material Maximum allowed packing width for the packaging material Maximum packing height of a packaging material

You can find exact details about the function of the individual fields in the field help.

Integration Packaging materials are a special type of product that can be used for packing or transporting goods. During packing, you must always enter a packaging material so that the system can create a handling unit .

1.2 Packaging Specification

PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 4 of 15

Definition A packaging specification is master data. The packaging specification defines all the necessary packing levels for a product in order, for example, to put away or transport the product. For a product, a packaging specification mainly describes in which quantities you can pack the product into which packaging materials in which sequence.

Use ● In printed form, a packaging specification is a set of instructions for the employee in the warehouse. More specifically, the work steps that you enter in a packaging specification are intended as information for the employee. In this way you can, for example, give the employee exact instructions as to where to place the label on a box, or how a product should be stacked onto a pallet. ● The system can determine packaging specifications during various processes (see below). Processes that determine packaging specifications use only parts or specific attributes from the packaging specification.

Structure

● Header Attributes such as the name of the packaging specification, user name of the creation user, status, and so on. ● Contents A packaging specification contains a product. However, some packaging specifications contain more than one product, or refer to other packaging specifications. ● Level You can map various packing levels in a packaging specification. Each level contains a target quantity, which defines how many times you can pack the previous level into this level. ● Element group For each level there is exactly one element group. However, you can reuse element groups in several packaging specifications. ● Elements Elements consist of a packaging material and/or a work step. ● Step A text with an identification, which you can use in one or more packaging specifications. ● Packaging material A product that is defined with a packaging material type in the product master.

Example for a Packaging Specification and Its Structure: Header: Name: PS1, Status: New Contents: product A, 1 piece Level 1: Target quantity one, element group EG1 Element group EG1: ● Element E1: packaging material ‘Small box’, work step ‘Place 1 piece upright in each box’ ● Element E2: additional packaging material ‘Label’, work step ‘Place label on upper left’ Level 2: Target quantity 50, shift quantity 10, element group EG2 Element group EG2: ● Element E3: packaging material ‘Pallet’, work step ‘Place boxes layer by layer onto pallet’

Integration The following figure shows which processes use the packaging specification, and using which components:

PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 5 of 15

In both the Inventory Collaboration Hub (ICH) and in Extended Warehouse Management (EWM), you can use the same packaging specification for an inbound delivery or an ASN that you then use for the Automatic Packing process.

Example Palletization data in EWM In your warehouse, you put away product A onto pallets for 50 pieces. Create a packaging specification with a level that contains the main packaging material Pallet and the contents Product A. For this level, enter the target quantity 50. In the process ‘Putaway’ for the inbound delivery, the system splits the quantity in the inbound delivery across multiple warehouse tasks, due to this packaging specification. For example, if a quantity of 100 pieces is delivered, then the system creates two warehouse tasks for 50 pieces.

Functions of the Packaging Specification The following functions are possible for packaging specifications: ● Create, copy, and activate (see also: Creation of Packaging Specifications) ● Determine (see also: Packaging Specification Determination) ● in mehrere Systeme verteilen.

!--a11y-->

Creation of Packaging Specifications Use You create a packaging specification to map in the system how you should pack a product.

Prerequisites You have made the following settings in Customizing: ● Define Number Range for Packaging Specification ● Define General Packing Parameters ● Define Group for Packaging Specification SAP also recommends that you make the (optional) settings under Maintain Structure of the Packaging Specification and Determination of Packaging Specifications . For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification .

Features When you access the Maintain Packaging Specification transaction, the overview screen appears first. This is divided into two parts: the upper screen is used

PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 6 of 15

to search for existing packaging specifications. The lower screen is a list in which you create new packaging specifications, and can display or change existing packaging specifications. From the list, you can go to the create , change , and display functions on the detail screen. This displays the structure of the packaging specification in the left screen area (in other words, the levels, elements, and the contents). The upper right screen area shows the most important header data for the packaging specification. The lower right screen area shows the detail data for the selected subobject of the packaging specification (in other words, for the level, the element, or the contents).

Activities 1. On the SAP Easy Access screen, choose Extended Warehouse Management ® Master Data ® Packaging Specification ® Maintain Packaging Specification . 2. The overview screen appears. Here you can access existing packaging specifications using the quick search or the advanced search. 3. 4. 5. 6.

To create a new packaging specification, choose Add New Line (symbol ). In the PS Group column, select a packaging specification. Select the packaging specification, then choose Change to access the detail screen. On the detail screen, you can first edit the header attributes for packaging specification, for example, you can enter a description or define the business key for the packaging specification ( Determination tab page). 7. You can define the structure of a packaging specification in Customizing (see also the IMG for SCM Basis under Packing ® Packaging Specification ® Maintain Structure of Packaging Specification ® Define Level Set ). If you work without level sets, then you should specify the structure of the specification in the packaging specification. You create levels and contents in the left screen area using the context menu (right mouse button). 8. When you create a packaging specification that describes the packing for a product, you enter the product in the Contents area. 9. For a level, you enter a target quantity and, where required, the minimum and shift quantity. Note that these quantities refer to the previous levels. Target quantity 10 for level 2 means, for example, that you should pack level 1 ten times into the main packaging material for level 2. In other words, 10 boxes onto one pallet. 10. For a level, you can either create the elements manually, or if you are working with a level set then the elements are proposed by the system. 11. To specify the main packaging material for a level, for example, create an element with HU relevance Main Packaging Material , and enter the packaging material in the relevant field. 12. The attributes Weight , Volume , and Dimensions (tab page) for the level are automatically determined by the system for the first main packaging material for a level. For this, the system adopts the attributes for tare and maximum weight (and/or volume, and/or capacity) and the dimensions from the product master for the packaging material. Choose HU Check to make the system calculate the attributes Loading and Total Weight (and/or Volume , and/or Capacity ). 13. When you save, you close a packaging specification in the detail area. 14. Choose Back (F3) to go back to the overview area. 15. In the overview area, you can activate one or more packaging specifications. The prerequisite for being able to determine the packaging specification in other processes is activation of the packaging specification (see also: Packaging Specification Determination). If the packaging specification contains all the data and you can use the packaging specification for the process, then you activate the packaging specification. 16. The overview area also offers you the functions Copy , New Version , Print Preview , and Delete .

!--a11y-->

1.2.2 Packaging Specification Determination Use You can use this function to determine a packaging specification using the business characteristics you have defined. The system uses the condition technique to do this. From the business characteristics predefined by SAP, you select those that are suitable for your processes (for example, product and vendor). A set of business characteristics forms a condition type. You can define different condition types for different processes. After you have specified a condition type, you can assign a packaging specification to these business characteristics. This means that you can, for example, specify that for a product P, vendor A, and process Automatic Packing in the Inbound Delivery , the system finds packaging specification PS. At the end of this process, handling units are created on the basis of the packaging specification found.

Integration The following processes use packaging specification determination: In Extended Warehouse Management (EWM): ● ● ● ● ● ●

Automatic packing in the inbound delivery Packaging material determination during warehouse order creation Packaging material determination in the outbound delivery Packaging material determination during deconsolidation Slotting Internal warehouse processes (such as determination of palletization data, determination of the operative unit of measure)

In Service Parts Planning (SPP): ● ATP Sourcing Rounding Rules ● MM Deployment Rounding Rules

Prerequisites ● You have made the Customizing settings for packaging specification determination. ● In the SAP standard system, Customizing settings for packaging specification determination have been predefined. However, you can make enhancements in the customer namespace. For packaging specification determination, you require the following: ○ Condition table ○ Access sequence ○ Condition type ○ Determination procedure ● You have created, specified, and activated determination records for a packaging specification.

Features For more information about condition technique, see the CA documentation for message control. Packaging specification determination runs using the same principles.

Activities The following describes how to create determination records in the system: 1. Choose Extended Warehouse Management ® Master Data ® Packaging Specification ® Maintain Packaging Specification . The Packaging Specification Overview screen appears. 2. Choose a packaging specification that already exists, or create a new specification, and choose Change (if you have already activated the selected packaging specification, you must first create a new version of this packaging specification). 3. On the determination tab page (Details for PS Header), enter a condition type or use the proposed condition type (see Customizing Define Level Set ). This screen always displays all condition records that you have created for the packaging specification. 4. Choose one of the proposed condition tables for which you want to create a condition record (If you have used the access sequence to assign more than one condition table to the condition type, perform this activity). You can configure these combinations as you want using Customizing. Choose OK . 5. Depending on the condition table/key combination you selected, make the mandatory entries (the current packaging specification number is entered automatically in the column). If necessary, change the sequence number of the condition record, to change the sequence of the determination. If, for example, you selected the key combination supply chain unit/product, then the subsequent mandatory entries are the supply chain unit and the product. If the system shows you condition records for other packaging specifications, then any condition record that is also displayed has the same key combination as the newly created record. Check whether there is an overlap of the two keys. 6. Save your condition record. 7. If there are no active packaging specifications, then you activate the packaging specification. If there is an active version of the packaging specification, then the condition records refer to the packaging specification number (regardless of the version), and the system takes this packaging specification into account during packaging specification determination. 8. You can use the Condition Maintenance transaction for activated packaging specifications, to add new condition records, or to change/delete existing records. Here you can also see an overview of all condition records, without reference to specific packaging specifications.

If the semantic key (in other words, the condition table, all fields of the condition table, and the condition sequence) are the same within a validity period, this results in an overlap of two condition records. If at least one condition record exists and it would not result in an overlap with condition records that already have active packaging specifications, then you can activate a packaging specification. If at least one condition record for the active packaging specification contains an error (in other words, will not be included in the determination), or if no condition record exists for this packaging specification, a yellow traffic light is displayed in the packaging specification overview. To find out whether the correct packaging specifications have been found, you can use transaction Switch On/Off Determination Analysis for Packaging Specifications to define whether the determination analyses for packaging specifications are stored in the database. Using the log, you can analyze which access sequences/condition tables the system used during the determination and which condition records were found.

!--a11y-->

Distribution of Packaging Specifications Use If you want to use packaging specifications in multiple SCM systems, you must distribute these packaging specifications to the other systems so that you are able to work with the same master data in all systems.

Prerequisites You have distributed the products and locations in all systems involved.

Features You can distribute the packaging specifications to different SCM systems by qRFC.

PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 8 of 15

Activities 1. In the distributing system, set up an RFC ABAP connection to them target system. To do this, on the SAP Easy Access screen choose Tools ® ALE ® ALE Administration ® Runtime Settings ® Maintain RFC Destinations (see also : Setting the RFC Destination). 2. In the distributing system, register a logical destination for the RFC ABAP connection in the qRFC Monitor. a. To do this, on the SAP Easy Access screen choose Advanced Planning and Optimization ® APO Administration ® Integration ® Monitor ® QRFC Monitor (Outbound Queues) . b. Enter the client and choose Execute . c. Choose Goto ® QOUT – Scheduler . d. Choose Edit ® Registration . e. Enter the RFC ABAP connection in the Destination field and copy the other proposed values. 3. In the distributing system, enter the RFC ABAP connection in Customizing for distributing the packaging specification. For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define RFC Connection for Packaging Specification Distribution . 4. In the distributing system, set the distribution indicator for the packaging specification groups for which you want to distribute packaging specifications to Source System. For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define Group for Packaging Specifications . 5. In the target system, set the distribution indicator for the packaging specification groups for which you want to receive packaging specifications from other SCM systems to Target System. For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define Group for Packaging Specifications . 6. If you do not want to work with only the distributed packaging specification in the target system, rather also with packaging specifications that you create in the target system, then you have to configure disjunctive number ranges to the number ranges in the source system in Customizing for the target system. The packaging specifications in the target system then receive different numbers and therefore cannot cause any conflicts with the distributed (or about to be distributed) packaging specifications. a. In the target system, create disjunctive number ranges for packaging specifications, work steps and element groups. For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define Number Range for Packaging Specification . b. Enter the new number ranges for work steps and element groups. For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define General Packaging Specification Parameters . c. Create a new packaging specification group, assign the new number range for packaging specifications to this packaging specification group, and set the distribution indicator to Local . For more information, see the Implementation Guide (IMG) for SCM Basis under Packing ® Packaging Specification ® Define Group for Packaging Specifications .

!--a11y-->

Unique Identification of Handling Units Use Since a handling unit is a physical unit consisting of packaging materials (load carriers/packing material) and the goods contained on/in it, each handling unit must be uniquely identifiable. You can do this by assigning an identification number. Within a client, this uniqueness can be ensured using a number range object. Across systems, unique identification is only possible by assigning a SSCC18 .

Prerequisites Ensure that you have made the following Customizing settings: 1. To configure the type of number assignment, choose the IMG activity Assign Number Range Intervals to Packaging Material Types . 2. To configure number assignment of the HU identification using a number range interval, choose the IMG activity Maintain Number Range Intervals for HU Identification . 3. If you want to ensure unique identification across systems, choose the IMG activities in the section SSCC Number Assignment According to EAN128 . For more information, see the Implementation Guide (IMG) for Extended Warehouse Management under Cross-Process Settings ® Handling Units ® External Identification .

Example If you want to edit or display a handling unit, you can only select the HU if this identification exists only once. If you permit multiple assignment of the same handling unit identification, then the system cannot find the handling unit you require, which means, for example, that scanner-supported processing is not possible.

!--a11y-->

SSCC Number Assignment According to EAN128 Use Because of global networking between manufacturers, transportation service providers, dealers, and consumers, communication between the instances involved in the supply chain is becoming more important. The basis of efficient processing is a common numbering standard, which is defined by international standardization organizations (UCC, EAN International). The UCC/EAN128 and one of its subcomponents, the Serialized Shipping Container Code (SSCC)/Number of the Shipping Unit (NSU), is defined as a part of these standards, and can be used to identify the handling units transported. This means that within the supply chain, the UCC/EAN128 and the SSCC can be used to transmit data about the handling unit from instance to instance, for example, via EDI with EDIFACT or EANCOM standards. You can uniquely assign SSCCs when you create handling units. SSCCs are used to identify and track handling units. You can collate the SSCC and other parts of the UCC/EAN128 into a valid bar code chain, or extract them from a bar code chain. The system generates the SSCC using a separate number range object.

Integration EAN128 numbering is integrated into the packing functions.

Prerequisites Before you can work with the EAN128 functions, you must request the basic number ILN2 (ILN = international location number) from either the UCC or EAN International.

Features When constructing handling units, you can use the packaging material to control that the system automatically assigns an SSCC/NSU. The number range used for this is determined by the system using the warehouse number. For more information, see the Implementation Guide (IMG) for Extended Warehouse Management under Cross-Process Settings ® Handling Units ® External Identification ® SSCC Number Assignment According to EAN128 ® Maintain SSCC Generation for Each Warehouse Number . You can also assign the SSCC/NSU can be assigned externally, and can be checked against an external number range, which the system finds using the same logic. At the same levels, you can enter the basis number for ILN2 that you require to generate the SSCC.

!--a11y-->

Packing at the Work Center Use Using packing in the work center, you can pack products into handling units (HU), and handling units into other handling units. For packing, there are various restriction options (filters) available for selection on the initial screen, for example, storage bin, handling unit, or delivery, which enable each user to optimize their worklist. On the left side of the work center screen, for example, you can use simple Drag&Drop to repack entire handling units, or to pack products into other handling units. The upper right screen area consists of tab pages that you can mainly use without a mouse. This transaction is particularly aimed at those users who physically pack products at work centers in the warehouse. The system supports entries using the keyboard or a scanner (where the necessary information is available as a bar code). You can also transmit the exact weight to the SAP system, using scales connected to the system, or you can print handling unit documents.

Prerequisites Ensure that you have made the required settings for packing in the work center, in Customizing and the SAP menu. For example, in the SAP menu you need to specify which storage bin is assigned to a work center. In Customizing, you specify which functions are executed at the relevant work center. The display for the different work centers is configurable. For example, in Customizing you can decide which of the available tab pages should be displayed for the user in the relevant work center. For more information, see the Implementation Guide (IMG) for Extended Warehouse Management ® Master Data ® Work Center ® Define Work Center Layout and Define Work Center .

Features PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Packing in the work center offers you the following range of functions: ● Scanning of ○ HU Identification ○ Product ○ Warehouse Task ○ Storage Section ● Creation of handling units ● Repacking of handling units ● Repacking of products ● Post Differences ● Changing handling units ● Deconsolidation of handling units You can configure packing in the work center in such a way that the system copies over frequently required data as default values for packing. In the Control area, you can make the following settings: ● ● ● ● ●

Standard storage bin Standard exception code Propose Destination HU indicator Propose Packaging Material indicator External number assignment on/off

The display is divided into the left and right screen areas. You use the left screen area mainly for navigation, and for quick repacking of handling units and products (only using the mouse). In the right screen area, you can request various detailed information about the individual entries. The left screen area groups the display according to the following objects: ● Storage section (displayed as ● Storage bin (displayed as

Activities Since you can assign various work center categories to the work centers in Customizing, you also have the option of calling up the various work centers separately in the menu. The corresponding input help is then restricted, depending on the work center, to the data you have configured in Customizing. For more information, see the IMG under Define Work Center . 1. To access the various types of work center, choose one of the following menu paths: a. From the SAP menu, choose Extended Warehouse Management ® Execution ® Packing - General b. From the SAP menu, choose Extended Warehouse Management ® Execution ® Quality Inspection and Count c. From the SAP menu, choose Extended Warehouse Management ® Execution ® Deconsolidation in Goods Receipt 2. Enter the relevant warehouse number, and use the input help to select the work center you require, if you have not assigned a work center to your terminal.

You can assign a work center to your terminal in the system, so that during packing, the system automatically fills in the correct warehouse number and your work center. To do this, from the SAP menu choose Extended Warehouse Management ® Master Data ® Work Center ® Define Master Data Attributes , and assign your terminal to the work center. You can also assign any scales that are connected to your work center.

Packing Using Drag and Drop In the area on the left, you can pack or unpack products in HUs, or pack HUs in other HUs as follows: ● If you want to repack products in other HUs, select the product and drag it into another HU. ● If you want to unpack products from other HUs, select the product and drag it to the storage bin. ● If you want to pack an HU in another HU, select an HU and drag it into another HU.

Packing Partial Quantities Using Drag and Drop 1. If you want to repack just one partial quantity of a product, double click a higher-level node (HU or storage bin) in the area on the left. 2. Choose the tab page Contents in the area on the lower right. All the product items of the HU or storage bin are now visible. 3. Enter the quantity that you want to repack in the Partial Quantity field and choose Enter . 4. Drag the item from the area on the right into the target HU or target storage bin in which you want to repack these partial quantities. a. To do this, click any cell in this row that is not ready for input. b. Then use drag and drop to drag this cell to the target area (destination HU or destination storage bin).

!--a11y-->

1.5 Automatic Packing in the Inbound Delivery Purpose Your vendor sends you inbound deliveries that do not contain any packing information about handling units. You can specify that the system automatically packs any unpacked delivery items. The packed goods can then be included in process-oriented storage control.

Prerequisites You have created and activated a packaging specification (see also: Creation of Packaging Specifications). ● Determination for the packaging specification is configured for your business characteristics (for example, vendor and product). (see also: Packaging Specification Determination) ● You have configured the determination procedure for automatic packing in Customizing. For more information, see the Implementation Guide (IMG) for Extended Warehouse Management under Goods Receipt Process ® Inbound Delivery ® Define WM-Specific Settings for Document Types .

Process 1. An inbound delivery notification arrives in Extended Warehouse Management (EWM) via the ERP interface. 2. When you activate the inbound delivery notification, the system simultaneously creates the handling units (HU), where the vendor has sent you the HU data. Moreover, at this time, the system calls packaging specification determination for the unpacked items, using the determination procedure you have defined. 3. If the system finds a packaging specification, it creates handling units according to the packaging specification. When creating packaging specifications, you should ensure that the HU Check function does not display any errors in the log. The system can only perform automatic packing successfully if the packaging specification contains all HU-relevant data (in particular, packaging material, target quantity, and product).

Page 12 of 15

Purpose Packing during warehouse task confirmation offers you a transaction that supports you during warehouse task confirmation, in processes that use printed documents. During picking, you can assign product warehouse tasks and handling unit warehouse tasks to pick-handling units. You can divide a product warehouse task between several pick-handling units. The system can assign the pick-handling unit identification, or you can do this manually.

Process 1. 2. 3. 4. 5.

Create a new entry for the pick-handling unit in the system. Enter a default packaging material. If required, enter a handling unit identification. Create a handling unit. During confirmation of the warehouse task, assign the pick-handling unit as the destination handling unit.

Results The product or handling unit is included in the pick-handling unit.

Examples A warehouse order contains 20 product warehouse tasks, and 4 pick-handling units proposed by the system. The picker identifies 4 boxes as pick-handling units. The picker performs picking and notes down the pick-handling unit into which he or she places each product. When you enter data in the foreground, you assign the proposed pick-handling units to the appropriate warehouse tasks during confirmation (for more information, see the input help).

!--a11y-->

Deconsolidation Using Radio Frequency Use You are able to execute deconsolidation using a Radio Frequency (RF) presentation device.

Prerequisites You are logged on to the RF environment.

Features · Logging on to a work center For most of the transactions within the main menu for deconsolidation you need to log on to a certain work center to get proposals for several input fields. · Creating multiple handling units (HUs) The creation of multiple empty putaway HUs can be used as preparation for deconsolidation. · Creating a single HU The creation of a single empty putaway HU can be used as preparation for deconsolidation. · Deconsolidating HUs Deconsolidation is the repacking/sorting of items from the deconsolidation HU into several putaway HUs. Repacking is based on transfer order (TO) confirmation. After the TOs have been confirmed, a new TO is created that is then used for putaway. Sorting occurs by the consolidation group which is copied from the activity area of the final putaway bin to the product TO. · Deconsolidating HUs manually Deconsolidation can also take place without you logging on to a work center. In this case, the system does not propose a putaway HU. Instead, you have to enter the putaway HU manually. The system still checks if the destination HU is valid for the selected TO. · HU overview The HU overview screen provides an overview of the deconsolidation HU that you want to deconsolidate, for example, the number of open TOs, weight, and volume. · Creating a single HU manually You can create a putaway HU without logging on to a work center. In this case, the system does not propose a packaging material or a bin. The creation of a single empty putaway HU can be used as preparation for deconsolidation. · Changing HUs In this RF transaction, you can close a putaway HU, delete an empty HU, convert a deconsolidation HU into a putaway HU, and condense a deconsolidation HU. Whenever a putaway HU becomes full, you have to close the HU in order for it to be ready for the next process step such as putaway. If you have created a HU in the system that you no longer need, you can delete it. To deconsolidate nested HUs, you have to condense them first.

1.8 Packing using Radio Frequency Use You are able to execute packing using a Radio Frequency (RF) presentation device.

Prerequisites You are logged on to the RF environment.

Features · Logging on to a work center For most of the transactions within the main menu for packing, you need to log on to a certain work center. Especially if you work with the function ‘Repacking HUs automatically’ or the function ‘Repacking HU items automatically’, the system will consider all HUs located at the work center to propose destination HUs. · Creating a single handling unit (HU) The creation of a single empty HU can be used as preparation for packing. · Repacking HUs automatically Packing HUs means consolidating several pick HUs into a destination HU. The system proposes the destination-HU based on the consolidation group for a scanned pick HU. If all repacked HUs contain the same consolidation group, the destination HU is also assigned to that consolidation group. · Repacking HU items automatically Packing HU items means deconsolidating several pick HU items into destination HUs. The system proposes the destination HU based on the consolidation group of the pick TO that belongs to the scanned HU item. If all repacked HU items contain the same consolidation group, the destination HU is also assigned to that consolidation group. · Creating a single HU manually You can also create a new HU without logging on to a work center. In this case, the system does not propose a packaging material or a bin. The creation of a single empty HU can be used as preparation for repacking HU items or HUs. · Repacking HUs manually You can also repack HUs without logging on to a work center. In this case, the system does not propose a destination HU. Instead, you have to enter the destination HU manually. The system still validates the consolidation group of the destination HU against the consolidation group of the pick HU. · Repacking HU items manually You can also repack HU items without logging on to a work center. In this case, the system does not propose a destination HU. Instead, the user scans the destination HU. The system still validates that the consolidation group of the HU item matches the one of the destination HU · HU maintenance You can use HU maintenance to check and/or change the weight and volume of a HU, for example.

Printing Handling Unit Documents Use Extended Warehouse Management (EWM) can use this function to automatically print lists or labels according to your Customizing settings, when you work with handling units (HUs). The documents can contain information about the contents, destination, owner, and data necessary for further processing of the handling unit. You can use this function in the warehouse management monitor, from the user interface for handling units, to perform or repeat printing for a handling unit.

Integration ● Printing of handling unit documents is based on SAPscript texts and SAP Smart Forms as form templates. ● EWM uses the Post Processing Framework (PPF) for message control. ● Additionally, EWM uses condition technique in the schedule condition for the PPF, to determine the printer, the form type, and the spool parameter.

For more information about the structure and Customizing for the Post Processing Framework, see the SAP Library under SAP NetWeaver Components ® SAP Web Application Server ® Basis Services/Communication Interface (BC-SRV ) ® SAP Communication: Configuration (BC-SRV ) ® Business Workplace and Services (BC-SRV-OFC) ® Generic Business Tools for Application Developers (BC-SRV-GBT) ® Post Processing Framework (BC-SRV-GBT) . For more information about the condition technique, see the SAP Library under mySAP Customer Relationship Management ® CRM Enterprise ® Enterprise Sales ® Sales Management for Commercial and Industrial Customers ® Basic Functions ® Condition Technique.

Prerequisites You have made the Customizing settings for the PPF. ● You have defined the PPF action definitions with the relevant processing types. In Customizing for the PPF action definition, you have defined the following data:

○ Processing time ○ Scheduling ○ Determination technique ○ Rule type ○ Action aggregation You have defined the PPF conditions for the defined PPF action definitions. You have made the Customizing settings for the condition technique. ○ You have defined condition tables. In Customizing, you have defined your condition tables from the field catalog, which SAP delivers. You have selected fields from the field catalog as key fields. These fields represent the condition under which the condition technique finds the condition record. If a data record transferred by EWM matches your key fields, then condition technique finds the matching condition record. In Customizing, you have defined condition types, and therefore the access sequence to the condition tables to search. In Customizing, you have assigned your condition types to the relevant condition schemas. The condition schema specifies the conditions that you permit for determining data (such as printer, form type) and specifies the sequence (access sequence) in which condition technique should consider them. In Customizing, you have assigned the condition schema to the application object (warehouse process type, packaging material type, work center). In Customizing, you have defined the condition maintenance group. You need the condition maintenance group to create condition records. The condition maintenance group specifies the condition tables and therefore the key fields. You have defined the logical conditions that you want to use in the condition records. You have defined warehouse-number-specific print settings (in particular the spool parameters).

Features For printing handling unit documents, the following action definitions are supported in the PPF in the application /SCWM/WME in the action profile /SCWM/HU . You have created these action definitions for each form type. This enables you to simultaneously print several different documents, for example, printing a HU content note and printing HU labels. An SAP Smart Form is available for each action definition. The system only supports printing of Smart Forms. The following table gives you an overview of the action definitions and their corresponding Smart Forms forms. You specify the assignment between action definition and Smart Form form in the created condition records. Action definition

When you save handling units or confirm a warehouse task, the system calls the PPF and starts an attempt to print. The decision whether to print is dependent on the condition records that are found in the schedule condition. If there is a condition record in which the PPF action definition matches the current PPF action definition, the PPF triggers the executing method and printing. This only happens if the logical condition is fulfilled, if one is entered in the condition record. In the work center, you can also trigger manually using a button. During printing or repeat printing, you can also execute PPF action definitions for which no condition records were created. However, since this means that the necessary data such as printer, form name, and spool parameters cannot be determined, you must enter this data manually. During printing, both the application and the PPF write data into tables. You must reorganize these tables manually. To do this, use report /SCWM/R_REORG_HU_WO_PRINT . During printing, the PPF writes a determination log and a processing log. You can switch these logs on and off, since they can become large. To do this, use parameter /SCWM/HU_PRT_PROT , where 'X' means that the system writes the log.

Activities ● EWM automatically triggers the print run from processing, or you trigger it manually. ● EWM calls the PPF and transmits the application data. ● The PPF determines the PPF action definitions you have defined in Customizing for the PPF application /SCWM/WME and the PPF action profile /SCWM/HU . ● The PPF calls the schedule condition that corresponds to the PPF action definition. ● In the schedule condition, the PPF calls determination in the condition technique. ● Determination of the condition technique returns the relevant condition record. This determines the printer, spool parameters, and the Smart Forms form. ● PPF lists the current application data. ● The system determines the function module that corresponds to the Smart Forms form, and calls this function module using the application data. ● PPF saves the action that was executed and the logs that were written.
