• What is the cause and solution for SAP error message /SAPDMC/LSMW083 - Multiple file definitions assigned to source structure '&' ?

  The SAP error message /SAPDMC/LSMW083 Multiple file definitions assigned to source structure '&' typically occurs in the context of the Legacy System Migration Workbench (LSMW) when you are trying to define a source structure for data migration. This error indicates that there are multiple file definitions associated with a single source structure, which is not allowed.
  Cause:
  
  
  Multiple File Assignments: The primary cause of this error is that the same source structure has been assigned to more than one file definition in the LSMW project. Each source structure should only be linked to a single file definition to avoid ambiguity during the data import process.
  
  
  Configuration Issues: There may be a misconfiguration in the LSMW project settings where the same source structure is inadvertently linked to multiple files.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Review File Definitions:
  
  Go to the LSMW project and check the file definitions assigned to the source structure in question.
  Identify all the file definitions that are linked to the source structure.
  
  
  
  Remove Duplicate Assignments:
  
  If you find that the same source structure is linked to multiple file definitions, you need to remove the duplicate assignments.
  Ensure that each source structure is only associated with one file definition.
  
  
  
  Adjust Source Structure:
  
  If necessary, you can create a new source structure for the additional file definitions that need to be used. This way, you can maintain separate definitions without causing conflicts.
  
  
  
  Test the Configuration:
  
  After making the necessary adjustments, test the configuration to ensure that the error no longer occurs and that the data migration process can proceed smoothly.
