  Solution:
  
  
  Check Table Existence and Activation:

  Ensure the user or background job has the necessary authorizations to read customizing tables.
  Check authorization objects related to customizing and FI document processing.

  Go to transaction OBA7 (Document Types) or related customizing paths to verify document status management settings.
  Ensure that the entries in T160AT are consistent and complete.
  
  
  
  Transport and System Consistency:
  
  If the error appeared after a transport or system upgrade, check transport logs for errors.
