  Custom Code Issues: If there are custom enhancements or modifications in the output processing logic, they may not be handling certain scenarios correctly.
  Inconsistent Data: Data inconsistencies in the master data or transactional data can lead to issues when the system tries to fill the communication structure.
  
  Solution:
  
  Check Output Configuration: Review the output determination configuration for the relevant document type. Ensure that the output type is correctly defined and that the necessary condition records exist.
  Validate Data: Ensure that all required fields in the document are filled out correctly. Check for any missing or incomplete data that might be causing the issue.
