• What is the cause and solution for SAP error message /SAPDMC/LSMW_OBJ_040002 - No source structure is assigned to target structure &. ?

  The SAP error message /SAPDMC/LSMW_OBJ_040002 No source structure is assigned to target structure &. typically occurs in the context of the Legacy System Migration Workbench (LSMW) when you are trying to perform data migration. This error indicates that there is a mismatch or a missing assignment between the source structure and the target structure in your LSMW project.
  Cause:
  
  Missing Assignment: The source structure has not been assigned to the target structure in the LSMW project.
  Incorrect Configuration: The configuration of the LSMW project may not have been completed correctly, leading to the absence of the necessary mappings.
  Data Model Changes: Changes in the data model or structure definitions in the target system may not have been reflected in the LSMW project.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the LSMW Project Configuration:
  
  Go to the LSMW transaction (LSMW).
  Open your project and navigate to the "Maintain Source Structures" section.
  Ensure that the source structure is correctly defined and that it is assigned to the appropriate target structure.
  
  
  
  Assign Source Structure to Target Structure:
  
  In the "Maintain Source Structures" section, check if the source structure is linked to the target structure.
  If it is not linked, you need to create the assignment. This can usually be done in the "Maintain Field Mapping and Conversion Rules" section, where you can map fields from the source structure to the target structure.
  
  
  
  Review Field Mapping:
  
  Ensure that all necessary fields from the source structure are mapped to the corresponding fields in the target structure.
  If there are any missing mappings, add them accordingly.
  
  
  
  Check for Data Model Changes:
  
  If there have been recent changes to the data model in the target system, ensure that the LSMW project reflects these changes.
  Update the target structure definition if necessary.
  
  
  
  Test the Configuration:
  
  After making the necessary adjustments, run a test to ensure that the data migration works without errors.
  
  
  
  Related Information:
  
  Documentation: Refer to the SAP Help Portal or the specific documentation for LSMW for detailed instructions on configuring source and target structures.

  SAP Notes: Check for any SAP Notes related to LSMW and the specific error message for additional guidance or known issues.
  
  By following these steps, you should be able to resolve the error and successfully complete your data migration using LSMW.
