Hi,

is step by step process .

Step-by-Step Guide for using BAPI in LSMW

Note! The screen prints in this article are from ECC 5.0. They may differ slightly in other versions.

Introduction:

This document details the usage of BAPI in LSMW. We have used the example of migration of the purchase order data into SAP.

Pre-requisites:

It is assumed that the reader of this article has the minimum knowledge required on the Business Object, BAPI, Message Types and IDoc Types.

Step-by-Step Procedure:

Details of the BAPI used in this scenario:

Business Object: BUS2012

Method: CreateFromData

Details of Message Type and Basic IDoc Type:

Message Type: PORDCR

Basic IDoc Type: PORDCR02

Let’s have a look at the BAPI first, before proceeding to the LSMW:

1. Go to Transaction BAPI

2. Click on Search Button

3. Enter the value “BUS2012” and select “Obj.type(Technical Object Name”

4. Press ENTER

5. Following screen appears:

6. On the left side of the screen, Expand the “PurchaseOrder”.

7. Select “PurchaseOrder” and double-click on the same for details.

Building LSMW using BAPI:

1. Go to Transaction LSMW.

2. Enter the Project, Subproject and Object information and click on CREATE.

3. Enter the descriptions for Project, Subproject and Object as prompted.

4. Now select Settings à IDoc Inbound Processing

5. “IDoc Inbound Processing” screen appears. Enter the required details as shown below:

6. Click on “Activate IDoc Inbound Processing”.

7. Click on “Yes” when prompted for “Activate IDoc Inbound?”

8. Hit on “Back” to return to the main screen.

9. Click on Continue (F8). Following Screen appears:

10. Select the Step 1 “Maintain Object Attributes” and select “Execute”.

11. Select the radio button “Business Object Method” and enter the following details:

Business Object: BUS2012

Method: CreateFromData

Hit ENTER

12. Save and click on BACK button. Following information message is displayed.

13. Now select step 2 “Maintain Source Structures” and click “Execute”.

14. In this step, we need to maintain the source structure. In our example, lets consider the example of a file with 2 structures Head and Item data as shown below:

Click on Create and name the source structure as HEADERDATA. Now select HEADERDATA and click on “Create” again to create the child structure. Following popup appears:

Select “Lower Level” and click on Continue. Enter the Item data structure name.

Click Save and hit BACK button to go to the main screen.

15. Select step 3 “Maintain Source Fields” and hit execute.

16. Enter the fields as shown below:

17. Click SAVE and return to main screen.

18. Select step 4 “Maintain Structure Relations” and click Execute.

Select E1PORDCR and click on CREATE RelationShip. Following screen appears:

Select HEADERDATA and hit ENTER

Similarly do the same for the structure E1BPEKKOA, E1BPEKPOC and E1BPPEKET.

Click Save and return to main screen.

19. Select the step “Maintain Field Mapping and Conversion Rules” and click on execute. Maintain the Field Mapping as seen below:

20. Select step 7 “Maintain Source Files” and provide the link for the test file created. (Create a test file with the same structure as defined earlier).

Save and return to main screen.

21. Select the step “Assign Files” and click on Execute.

Assign the file provided to the source structure. Here the same file is provided for both the structures.

Save and return to the main screen.

22. Select the step “Read Data” and click on Execute.

Click on Execute.

Return to the main screen.

23. Select the step “Display read data” and click on execute.

Click on the structure name to get the field level values.

24. Return to main screen and now select “Convert Data”.

25. Return to the main screen and select “Display Converted data”.

26. Return to main screen and select “Start IDoc generation”.

27. Now select the step “Start IDoc Processing” on the main screen.

28. Return to main screen and click on “Create IDoc overview”. Here the data record and status records of the IDoc could be viewed:

Hi

BAPI - BAPIs (Business Application Programming Interfaces) are the standard SAP interfaces. They play an important role in the technical integration and in the exchange of business data between SAP components, and between SAP and non-SAP components. BAPIs enable you to integrate these components and are therefore an important part of developing integration scenarios where multiple components are connected to each other, either on a local network or on the Internet.

BAPIs allow integration at the business level, not the technical level. This provides for greater stability of the linkage and independence from the underlying communication technology.

LSMW- No ABAP effort are required for the SAP data migration. However, effort are required to map the data into the structure according to the pre-determined format as specified by the pre-written ABAP upload program of the LSMW.

The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.

More and more medium-sized firms are implementing SAP solutions, and many of them have their legacy data in desktop programs. In this case, the data is exported in a format that can be read by PC spreadsheet systems. As a result, the data transfer is mere child's play: Simply enter the field names in the first line of the table, and the LSM Workbench's import routine automatically generates the input file for your conversion program.

The LSM Workbench lets you check the data for migration against the current settings of your customizing. The check is performed after the data migration, but before the update in your database.

So although it was designed for uploading of legacy data it is not restricted to this use.

We use it for mass changes, i.e. uploading new/replacement data and it is great, but there are limits on its functionality, depending on the complexity of the transaction you are trying to replicate.

The SAP transaction code is 'LSMW' for SAP version 4.6x.
