  Cause:
  
  Duplicate Document Number: The document number you are trying to use has already been assigned to another transaction. This can happen if the number range for document numbers is not properly configured or if there is an attempt to manually enter a document number that is already in use.

  Check Document Number: Verify the document number you are trying to use. Ensure that it is not already assigned to another document. You can do this by checking the relevant tables (e.g., MKPF for material documents).
  Use a New Document Number: If the document number is indeed in use, you will need to use a different, unassigned document number for your transaction.
  Review Number Range Configuration: Check the configuration of the number ranges for the relevant document type in the SAP system. Ensure that the number range is correctly defined and that there are available numbers.
  
  You can do this by navigating to the transaction code SNRO (Number Range Objects) and checking the settings for the relevant object.
  
  
  Consult with SAP Basis or Configuration Team: If you are unsure about how to check or modify the number range settings, consult with your SAP Basis or configuration team for assistance.
