  Check Mapping Configuration:

  Correct the Mapping:
  
  If you find discrepancies in the mapping, correct them by updating the mapping entries to ensure that each project is associated with the correct company code.
  
  
  
  Data Consistency Check:
  
  Perform a consistency check on the data being migrated. Ensure that all projects and company codes are correctly defined and that there are no orphaned entries.
  
  
  
  Consult Documentation:
