  Removing or adjusting fields in the source system if they are not needed.
  Ensuring that any custom fields are consistently defined in both systems.
  
  
  
  Check for Notes and Updates: Look for any SAP Notes or updates that might address known issues with the specific table or migration process you are working with.
