LSMW ( Legacy System Migration Workbench )

 

  • It is a ABAP Workbench tool which is used to transfer data from Non-SAP ( Legacy ) system to SAP system.
  • Here, we can migrate the legacy system data to SAP system.
  • Transaction code :- LSMW
  • LSMW works best for Master data ( Material Master, Client Master data ) which does not require to use much coding while using LSMW.
  • This method is more preferred by Functional SAP Consultants rather than technical Consultants for data migration.
  • We can export and Import a LSMW.

Difference between BDC and LSMW :-

  • LSMW is for functional consultants which does not require much coding, while BDC is designated for technical consultants.

For LSMW we need to understand three terminologies :-

1. Project :-

  • In this we specified the name of the data transfer project.
  • More than one sub project can be assigned to a project.

2. Subproject :-

  • It specifies the name of the subproject.
  • A subproject can have an unlimited number of objects.

3. Object :-

  • An object corresponds to a business object.
  • An object is assigned to a subproject.
  • Examples :- Material Master, Client Master etc.

Examples :-

  1. Project :- DataMigration

    Subproject :- Materials

    Object :- Matcreate

  2. Project :- DataMigration

    Subproject :- Materials

    Object :- Matchange

UPDATE Function Modules :- This is generally used to update the database record. Update Function Module can be called from the same system. ( Background RFC / trfc / grfc ) This is used to achieve generally the SAP LUW. Some time we use from performance perspective also. When COMMIT WORK gets executed then Update starts getting executed.

OR What is the T-Code for ...

Requirement :- let’s create a function module for sum of two numbers. 1. Creation of function group :- Step 1 :- Go to SE80 transaction code → Object Navigator. Step 2 :- From the drop down select function group. Step 3 :- Give a name of function group. Step 4 :- press enter. Step 5 :- Click on yes a popup screen will appear.
