Some times when the Master data are to be uploaded from a legacy system or from any other non connected, non SAP systems LSMW will come to the rescue. LSMW can be expanded as Legacy System Migration Workbench. This is to migrate the business entities into the CRM system. This tool actually contains following methods in which we can import data to CRM system:

 

  • Standard Batch / Direct Input
  • Batch Input Recording    
  • BAPI
  • IDOC.

 

Out of these methods we will have a look into the steps of the importing business partners using Idoc method.

After this step, idocs will be created which can be viewed in transaction WE05. I hope this might help who try to import the Business objects using Idoc method of LSMW. For illustration purposes i have combined partners and orders in few places. This is a guideline for LSMW Idoc input method.
