This error indicates that the system expects an internal number to be provided when an external number is being assigned.
  Cause:
  
  External Number Assignment Configuration: The system is configured to use external number assignment for certain document types, but it requires an internal number to be specified.
  Missing Internal Number: When creating or processing a document, the internal number (which is usually generated by the system) is not provided, leading to this error.

  Ensure that the document type is correctly configured for either internal or external number assignment as per your business requirements.
  
  
  
  Provide Internal Number:
  
  If the process requires an internal number, ensure that it is being supplied correctly in the transaction or program you are using.

  Review Number Ranges:
  
  Check the number range settings for the document type. Ensure that the number range is defined and that it allows for internal number assignment.
  You can check this in transaction SNRO (Number Range Objects) or through the relevant configuration path in SPRO.
  
  
  
  Consult Documentation:
