How to Create Transaction Codes from LSMW Projects

SAP LSMW stands for Legacy System Migration Workbench. It is a tool provided by SAP (Systems, Applications, and Products) that allows you to migrate data from non-SAP systems to SAP systems.

The LSMW tool provides a structured approach to extract, transform, and load data into SAP systems. It is commonly used during system implementations, data migrations, or system upgrades when data needs to be transferred from legacy systems to SAP.

Creation of Transaction Code from LSMW

There are two other ways to create Tcodes for any LSMW conversion object.

1. Creating Custom Program: A custom program can be created using function module "/SAPDMC/LSM_OBJ_STARTER". After creation of the custom program, a transaction code can be created using that program.

Related Transaction Code: 

  • Program creation : SE38
  • Transaction creation: SE93

Sample ABAP Program:

CALL FUNCTION '/SAPDMC/LSM_OBJ_STARTER'
  EXPORTING
    PROJECT                  = 'ZLSMW_PROJECT'
    SUBPROJ                  = 'ZLSMW_SUBPROJECT'
    OBJECT                   = 'ZLSMW_OBJECT'
*   X_CALLED_FROM_DXWB       = ' '
* EXCEPTIONS
*   NO_SUCH_OBJECT           = 1
*   OTHERS                   = 2
          .
IF SY-SUBRC <> 0.
* Implement suitable error handling here
ENDIF.

2. Creating Parameter Transaction: Second method to create a Tcode for LSMW is using the steps below provided.

  • Create Z-Tcode with Parameter Transaction(SE93).
  • In the default values for area, give transaction 'LSMW' and check the box for 'skip initial screen'.
  • In the name of screen field area section, provide the following.
                /SAPDMC/LSSCREEN-PROJECT = <Z-Project>
                /SAPDMC/LSSCREEN-SUBPROJ = <ZSub-Project
                /SAPDMC/LSSCREEN-OBJECT = <Zobject>
  • Save and Activate

Creating a Search Help and Assigning it to Another Table in SE11

In SAP ABAP, a search help is a feature that provides a user interface for searching and selecting data values from a list. A search help is essentially a dialog box that displays a list of possible values for a particular field or selection criterion. Once a search help is defined and assigned to a data element or domain, it can be used in various SAP applications, such as data entry screens, reports, and dialog programs. To use a search help in a program or report, you can call the function module "F4_HELP" or "F4IF_INT_TABLE_VALUE_REQUEST" to display the search help dialog box and retrieve the selected values. You can also customize the search help behavior and appearance using various parameters and options. There are two types of search help available in SAP ABAP: elementary search help and collective search help. Elementary search help is used to display a list of possible values for a single input field. It is used when the user needs to select a single valu...
