• What is the cause and solution for SAP error message DMC_GENERAL085 - File &1 is already assigned to migration object ?

  The SAP error message DMC_GENERAL085 indicates that a file you are trying to assign to a migration object is already associated with another migration object. This typically occurs during data migration processes using the SAP Data Migration Cockpit or similar tools.
  Cause:
  
  File Reuse: The file you are attempting to upload or assign has already been linked to a different migration object. This can happen if the same file is used for multiple migration tasks or if there was a previous attempt to assign it that was not properly cleared.
  Incorrect File Management: If files are not managed properly, it can lead to confusion about which files are assigned to which migration objects.
  
  Solution:
  
  Check Existing Assignments: Verify which migration object the file is currently assigned to. You can do this by checking the migration object settings or the file management section in the Data Migration Cockpit.
  Use a Different File: If the file is already in use, consider using a different file for your current migration task.
  Unassign the File: If you need to use the same file, you may need to unassign it from the previous migration object. This can usually be done in the migration object settings.
  File Naming Convention: Implement a clear naming convention for your files to avoid confusion in the future. This can help prevent the same file from being used in multiple migration tasks inadvertently.
  Consult Documentation: Refer to the SAP documentation or help resources for specific instructions on managing files and migration objects in your version of SAP.
