How to use BAPI

How to use BAPI_SHIPMENT_CHANGE ? Hi everyone.

I want to use BAPI_SHIPMENT_CHANGE for change 'Contents'.

You can see that info. on screen capture by following step. : VT03N -> Button - Means of transport and Packaging Matl for Currnet Shipment (Shift+F9) -> Double click 'Handling Unit'.

As you can see above, TRUCKID1 was packed with DO 10, 20, 30. When I change the 'Contents' with BAPI_SHIPMENT_CHANGE, the changing is successful but TRUCKID1 is unpacked. (it's my Problem)

So I'd like to know how to change 'Contents' with keeping pack status.

Current parameter for the bapi is like below.

HEADERDATA - SHIPMENT_N : shipment no.

HDUNHEADER - HDL_UNIT_EXID : TRUCKID1 - CONTENT

: TEST1,2,3

HDUNHEADERACTION - HDL_UNIT_EXID : C - CONTENT

Goods Movement Transaction - BAPI created by Venkateswaran K on Jun 5, 2012 1:32 PM, last modified by Venkateswaran K on Jun 5, 2012 1:54 PM Version 1 inShare

Scenario

At the time of implementation, we need to upload large amount master data and transactional data in the MM Module. For Example to Upload the initial stock. Secondly there may be a situation that we need to upload a large amount of Goods Movement transaction. In order to achieve that we can use the following BAPI. This document explains the steps to arrange the data and upload in the system using BAPI.

This document will provide a guideline with respect to your requirement. Use this BAPI template for all types of Goods movement transaction by Changing appropriate movement indicator, GMcode of header information of BAPI and execute it.

Pre-requisite

Arrange the Data in the following format. Preferably in the Excel format

Ths is a comprehensive list of data. You can use the relevent fields based on your movement type. But do not change the sequence. External Document Number - Any reference document number you need to maintain             

Movement Type - Movement type viz 561 311 etc Plant - plant code Material Number - Material code Quantity - Quantity Issuing Location - From Storage location Receiving Location - Receiving Storage location Purchase Document No - PO document Purchase Document Item No - PO item number Delivery Purchase Order Number - Delivery document no Delivery Item - Delivery item no Production Document No - Production doc no Scrap Reason - Reason code Document Date - Document date on which you post it Posting Date - Posting date

Header level flags

There are some header level flags for BAPI we set based on the movement type we execute.

GMCODE Table T158G - 01 - MB01 - Goods Receipts for Purchase Order 02 - MB31 - Goods Receipts for Prod Order

03 - MB1A - Goods Issue 04 - MB1B - Transfer Posting 05 - MB1C - Enter Other Goods Receipt 06 - MB11

Movement Indicator

Goods movement w/o reference B - Goods movement for purchase order F - Goods movement for production order L - Goods movement for delivery note K - Goods movement for kanban requirement (WM - internal only) O - Subsequent adjustment of "material-provided" consumption W - Subsequent adjustment of proportion/product unit material

BAPI - Details Name : BAPI_GOODSMVT_CREATE Header Data : Header, Code Item Details : Internal table that contain material details that we fetch from Excelsheet

CALL FUNCTION 'TEXT_CONVERT_XLS_TO_SAP' EXPORTING i_line_header = 'X' i_tab_raw_data = it_raw i_filename = loc_filename TABLES i_tab_converted_data = pcitab EXCEPTIONS conversion_failed = 1 OTHERS = 2. endform.

" UPLOAD_DATA

Set Header information

gmhead-pstng_date = sy-datum. "you can change it from the data you read from excl gmhead-doc_date = sy-datum. gmhead-pr_uname = sy-uname. gmcode-gm_code = '04'. "04 - MB1B - Transfer Posting

Set Item Details

loop at itemtab. itab-move_type = itemtab-mvt_type. itab-mvt_ind = ''. itab-plant = itemtab-plant. itab-material = itemtab-material. itab-entry_qnt = itemtab-qty. itab-move_stloc = itemtab-recv_loc. itab-stge_loc = itemtab-issue_loc. itab-po_number = itemtab-pur_doc. itab-po_item = itemtab-po_item. itab-move_reas = itemtab-scrap_reason. append itab. endloop.

Now Call BAPI

call function 'BAPI_GOODSMVT_CREATE' exporting goodsmvt_header = gmhead goodsmvt_code = gmcode * TESTRUN ='' IMPORTING goodsmvt_headret = mthead * MATERIALDOCUMENT = * MATDOCUMENTYEAR = tables goodsmvt_item = itab * GOODSMVT_SERIALNUMBER = return = errmsg.

Display errors if any clear errflag. loop at errmsg. if errmsg-type eq 'E'.

write:/'Error in function', errmsg-message. errflag = 'X'. else. write:/ errmsg-message. endif. endloop. You can use this BAPI template for Goods movement by setting appropriate header flags

Function Module: BAPI_MATERIAL_AVAILABILITY

Posted by Tuncay Karaca in ABAP Connectivity on Apr 26, 2007 9:45:52 PM inShare I have used BAPI_MATERIAL_AVAILABILITY in iWay project to create CheckMaterialAvailability web service. Firstly let's look at its documentation: Using this function module, you can determine the receipt quantity still available for a particular material in a certain plant according to ATP logic (MRPII). The availability check is carried out on transferring the material number, the plant and the input table (WMDVSX). The scope of the check, that is, which stocks, receipts and issues are to be included in the check is defined by the combination of checking group (material master) and cheking rule. In the function module, the system uses the checking rule defined in Sales & Distribution (A). You can overrule this checking rule by using an interface or a user-exit (exit_saplw61v_001). A similar procedure is also valid for the plant parameters. The customer number in the user-exit means that the plant selection can be controlled via the customer. If no plant parameters are given via the interface, the system uses the parameter 'WRK' saved in the user's fixed values. The results of the availability check are recorded in the output table (WMDVEX). This table contains dates and available receipt quantities (ATP quantities). The results of the check depends on the following entries:   

If no date and no quantity is transferred, the system displays the ATP situation from today's date into the future as the result. If only a date and no quantity is transferred, the system displays the ATP situation from the corresponding date as the result. If both a date and a quantity are transferred, the system calculates the availability situation for the quantity specified.

In the last two cases, the parameter 'DIALOGFLAG' is supplied. This can result in the following:   

' ' (blank) quantity completely available 'X' only partial quantity available or not available at all 'N' Material not included in the availability check (Material not relevant to the availability check)

The system also displays the end of the replenishment lead time (ENDLEADTME).

You can run BAPI_MATERIAL_AVAILABILITY for only one material, one plant, one unit at a time. But we needed to check availability for multiple materials at a time, so I wrote a Z* RFC which wraps BAPI_MATERIAL_AVAILABILITY. Simply Z* RFC accepts multiple materials in a table parameter, then call BAPI_MATERIAL_AVAILABILITY in a loop.

Here is how call it:

1. * 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.

Call BAPI Material Availability CALL FUNCTION 'BAPI_MATERIAL_AVAILABILITY' EXPORTING plant = ls_plant-werks material = it_material-material unit = it_material-unit check_rule = it_material-check_rule IMPORTING return = ls_return TABLES wmdvsx = lt_req wmdvex = lt_com.

Import Parameters:

PLANT: give a plant number MATERIAL: give a material number UNIT: unit of measure for the material CHECK_RULE: give a check rule, value table is T441R (Values Table for Checking Rule). If you don't give check_rule, the function module gets A (SD order).

Table parameter WMDVSX (Input table (date and quantity)):    

REQ_DATE: Requirement date. If no date and no quantity is transferred, the system displays the ATP situation from today's date into the future as the result. REQ_QTY: Required quantity. DELKZ: You can give MRP element indicator, it isn't obligatory. YLINE: You can give index number to each line for internal table processing.

Export Parameters:

RETURN: If something returns with this parameter, it shows something is wrong. After calling function module, firstly check this parameter. For example you can get a message like that: "Material MMM not maintained in plant" Table parameter WMDVEX (Output table (date and ATP quantity)):   



REQ_DATE: Requirement date from import table WMDVSX. REQ_QTY: Required quantity from import table WMDVSX. COM_DATE: Committed date. If there is available quantity for required quantity, it is same as REQ_DATE. It could be different than requirement date; it means there is no available quantity on required date, but it is available in the (near) future. COM_QTY: Committed quantity. It must be same as required quantity.

If even you don't give (fill out WMDVSX table), any required quantity,

you get a result in table WMDVEX.

But requirement date was accepted today's date, and required quantity was accepted as much as big number like 9,999,999,999.000.

COM_QTY (committed quantity) shows available quantity on COM_DATE (committed quantity).

Its documentation says export parameter DIALOGFLAG can be used to see whether required quantity is available or not ( ' (blank): Available, 'X': Not available or partially available, 'N': Material not relevant to the availability check ). But as you see I didn't use DIALOGFLAG. I used table WMDVEX to do that. If I require 600 EAch material, and if it gives me less than this number as committed quantity, it means there is no available quantity for my requirement.

If you want to compare the result, you can use transaction CO09 (Availability Overview). It gives the same result as BAPI_MATERIAL_AVAILABILITY does.

On SDN forums there are several discussions keep going about BAPI_MATERIAL_AVAILABILITY:        

bapi_material_availability returning strange values BAPI_MATERIAL_AVAILABILITY CALLING BAPI in ABAP program BAPI for displaying stock How to get material availibility What is the difference between CO09,MD04 and MMBE? Get real stock available to sell. ATP Quantity Calculation Logic in transaction in CO09

Here is another link mentions BAPI_MATERIAL_AVAILABILITY: 

BAPI_MATERIAL_AVAILABILITY

Have you used BAPI_MATERIAL_AVAILABILITY? http://www.newtosap.info/2012/06/create-custom-bapi-easily.html Create a custom BAPI easily BAPI's are very useful in SAP to perform some business function as well as to exchange data / interact between different SAP systems or Non SAP systems as well. Though SAP provides a whole bunch of ready to use BAPI's, one can create there own BAPI(s) easily if required. Steps involved in creating a custom BAPI: 1 ) Create a BAPI import structure Example : I am creating a BAPI import structure ZABPI_ADIIMPORT having MATNR component.

2 ) Create a BAPI return table structure: I am creating a structure with matnr and werks , this will be output table of my BAPI.

3) Go to SE37 and create a custom BAPI FM(Function Module). ZBAPI_GET_WERKS is the bapi name. All custom BAPI FM’s should begin with ZBAPI* Make the FM remote enabled by selecting Remote Enabled Module. All BAPI FM’s are RFC enabled.

Now add the bapi import structure we created in import tab. Always remember to tick Pass by value since BAPI FM which is a RFC enabled FM cannot use pass by reference.

In the export tab we will put BAPI return parameters. BAPIRETURN is a standard BAPI return structure. In the source code of the program we need to make use of this parameter to show success or failure status along with messages.

In the tables we will use our BAPI export table structure we created. We always use LIKE for tables.

4) Source code: Add the logic of the FM here. FUNCTION ZBAPI_GET_WERKS. *"---------------------------------------------------------------------*"*"Local Interface: *" IMPORTING *" VALUE(MATNR) TYPE ZBAPI_ADIIMPORT-MATNR *" EXPORTING *" VALUE(RETURN) TYPE BAPIRETURN *" TABLES *" ZTABLE STRUCTURE ZBAPI_ADIEXPORT *"---------------------------------------------------------------------select matnr werks from marc into TABLE ztable where matnr eq matnr. if sy-subrc eq 0. "Update BAPI return table accordingly to show success here else. "Update BAPI return table accordingly to show failure here ENDIF. ENDFUNCTION.

Logic of our BAPI is simple; it fetches matnr and werks value from marc table based on input matnr values and fills the BAPI table. Lets test the FM, click execute and input a test data

ZTABLE will be filled with values from marc table corresponding to input matnr value

5 ) Place this Function Module in to BOR(Business object repository) using the T-code SWO1. Provide the name of the object and press create button.

Add our Custom BAPI FM using Utilities = > API Method = >Add Method

Press next to see the parameters involved

Press next and it will ask you that method has not been implemented, and will ask for confirmation to generate a template. Press Yes

Go back and change the BOR status to Implemented.

Next generate the BOR by clicking

After generation of BOR , release the BOR.

We can test the BOR by clicking execute

Test is similar to FM test and we can see the result

Thats it :) . Our custom BAPI is now created. Now you can use this BAPI like other BAPI.To learn how to use BAPI in reports , refer

BAPI- What is it and how its used [Part 1] BAPI- What is it and how its used [Part 2] BAPI- What is it and how its used [Part 1] BAPI's are basically function modules only. ALL BAPI's are remote enabled function modules which enables to access via non SAP systems. A remote function enabled FM(Function Module) will be attached to BOR(Business Object Repository) , then only it is termed as BAPI. Using BAPIs you can develop applications without detailed knowledge of the underlying R/3 System. Each BAPI is having its own business application and area. The integration between R/3 and third-party software, legacy systems, and custom-developed software can be achieved via BAPI.

BAPI explorer with TCODE 'BAPI'.

BAPI explorer All BAPI's are arraigned according to the business area. Details documentation is also available for some BAPI's to show the usage of the BAPI

Documentation of each BAPI

BAPI since its RFC enabled FM, has no exceptions. There are BAPI return tables which can be used to analyze the success/failure of the process. Since BAPI's are basically FM only , we call BAPI the same way we call a normal FM.

Its very important to select appropriate BAPI and also to pass the data in a way required by BAPI. Go through all I/O structures for the BAPI selected to understand this better. We can also call BAPI of other SAP systems. Just mention destination and you are good to go. Ex: call function 'BAPI_SALESORDER_GETSTATUS' destination 'PW2' exporting salesdocument = order importing return = return tables statusinfo = statusinfo.

We need to call BAPI_TRANSACTION_COMMIT after each BAPI call to finalize or commit the change or if some error occurs and we have identified the errors we need to use BAPI_TRANSACTION_ROLLBACK to rollback the changes made if any.
