Legacy System Migration Workbench LSMW: Legacy System Migration Workbench As we all know LSMW is very helpful and easy when it comes to upload heavy data into SAP system in less time. It’s a tool used to upload master data in SAP Let’s create a LSMW to upload condition type PR00, to upload new price for large set of materials. Process: Go to transaction LSMW and to will take you to below screen –
SAP has provided user to segregate there LSMW’s in a proper manner by divided it into 3 parts “Projects, sub projects and objects”. Click on the highlighted button to create a new LSMW a pop up will appear as shown below asking for project name and description -

This is the overview screen of LSMW. Step1: Maintain object attribute Here in this step we decide which process we used to input out legacy data into SAP system, SAP has provided some of the process as shown below
Standard Batch/Direct Input Batch input recording Business object method (BAPI) IDOC (Intermediate document)

Now click on create button highlighted in above screen to create a new recording, system will ask you name the recording and describe it as shown below-
As soon as you name the recording and describe it system will ask for which transaction you want to do recording. Recording: As the name goes recording means recording step by step process how you key data in that particular transaction, system uses this recorded example as skeleton to feed those thousands of entries which you hold in sheet.

Click on the highlighted entry of the recording a pop up will appear as shown
9
LSMW by Mohammed Mubeen Ahmed
SAP CRM
Legacy System Migration Workbench Name the field as KSCHL in name column and then describe it as condition type in next name field, and keep PR00 as default value if all of the records you want to feed in is on PR00 only otherwise make it blank. In this example I have all records for PR00 only so I will keep it as default only, as shown below-
In the same way click on second field and repeat the process again as shown below As I don’t want sales organization to be default I removed it from default value which was recorded by system.
Repeat the same process for rest fields in the list and it always better to keep name of field as same highlighted in above screen (standard) this will help in future step 5 when we try to map these fields. This is how screen looks after you complete the process
10

1. Name of the fields 2. Default values 3. Options like default all, default, reset, delete field, add field repeat recording for quick access.
This complete the first step and as soon as you save changes system takes you to below screen for next step, cursor goes to next step automatically as shown below

Step 2: Maintain source structure Source structure is all about structure of you data file, it’s like a group name, system ask you to key the name and description of structure, give some sensible name as shown below-
Press ok and this is how our structure looks like
12

Step 3: Maintain source field Source fields: It’s a set of field’s names which we have in our source data file and details about them
Click on execute or press F8 system will take you to below screen.
Click on highlighted button of table content and system will take you to below screen where you can feed in all source fields.
13

Fill all the fields in this table with their technical name, data type, field length and description as shown above. And it should be in the same order as you have positioned in the source data file with correct process as per transaction. Input file: Source data file
14
LSMW by Mohammed Mubeen Ahmed
SAP CRM
Legacy System Migration Workbench It’s always betted to keep source data file in text format with tab delimited as shown above.
The above screen shows that the recently created source structure contains the recently create source fields, both highlighted source structure and fields. Step 4: maintain structure relation This is the step where you relate your source structure which contains all source fields to the recording which we created in first step, it’s just an assignment.
System automatically relates the recent created source structure with the recording which we have created in first step, LSMW by Mohammed Mubeen Ahmed SAP CRM
15
Legacy System Migration Workbench
Just click on change button
and then save the transaction.
Step 5: Maintain field mapping and conversion rule Field mapping: This is the critical and most important step in LSMW; it is used to map the fields of recording (Step1) with the source structure fields (step 4&5).
16

System shows all the fields which we have recorded in first step as shown above.
17
LSMW by Mohammed Mubeen Ahmed

Just make sure highlighted radio button is opted then system will map the same field name from recording with same field name in source structure field name.
18

You can see that under target field, name of field is KSCHL from recording name REC8 (step 1) and under source filed, name is the field is also KSCHL of source structure PR00_SOURCE_STRUCTURE (step 4)
19

Click on the accept proposal and continue doing same for rest all fields. When it comes to dates and values system smartly ask for the format of date as shown below
System gives this message after auto mapping completion.
20
LSMW by Mohammed Mubeen Ahmed
SAP CRM
Legacy System Migration Workbench This is how screen looks after mapping gets completed.
Step 6: fixed values, translation and user define routine. This is used to give fix value to some filed after mapping and to validate the date by using user define routine. We will skip this step as this is optional and of no use for our LSMW.
21
LSMW by Mohammed Mubeen Ahmed

Legacy System Migration Workbench Step 7: specify file
Specify file: It is the step where we show and specify where we store our source data file in our directory.
Place the cursor “on the PC” first line and click on create button directory path
22
LSMW by Mohammed Mubeen Ahmed
a pop will appear asking for

1. File path and file name. 2. Type of delimiter source data file contains (its tabulator in our case). 3. Whether file contain headings (field name) at the starting of file.
23
LSMW by Mohammed Mubeen Ahmed

Here we just assign our source data file to the source structure which we have created in step 4.
24
LSMW by Mohammed Mubeen Ahmed

Legacy System Migration Workbench Step 9: Read data
This will read all the records from the source data file, system shows that what will be the date and value format as shown below-
After successful execution system display how many records has been traced from the source data file.
25

File path where system stores the traced data from source date file, file path ends with read. Source structure which has been assigned to source data file. Field name of source fields of source structure. Value extracted again field names from the source data file.
Step 11: Convert data System converts the list of records traced from source data file into its own transactional format of VK11 in this step.

Step 13: Create batch input session In this step we will create batch session which can be run in next step to run the heavy source data file.
Highlighted is the session name which system gives automatically.
33

An information pop up appears saying these many records has been created in this batch folder.
Step 13: Run batch input session In this step we will run the batch input session which we had set in last step.
34

Legacy System Migration Workbench Select the latest session based on session name and user id and click on highlighted process button
A pop up appears as shown below-
Process/foreground: It runs the file in foreground, this is recommended when you run sample file to see how system creates entry through batch input recording. Background: System runs the file in background, this is recommended when you run huge file to avoid manual work of pressing entry every single time.
35

Legacy System Migration Workbench Extended log: By enabling this system give detail analysis or log about both successful and unsuccessful transactions. This is how analysis screen looks like-
Go to VK13 (display mode of condition record) transaction and check random entries to confirm created entries are accurate and correct. This is the last step involved LSMW creation.
