  Cause:
  
  Exhausted Number Range: The internal number range for the document type has been completely used up, and there are no more numbers available for assignment.

  Create New Number Range:
  
  If necessary, you can create a new number range interval for the document type and assign it accordingly.
  
  
  
  Check Authorizations:
