  Solution:
  
  Check Document Number: Verify that the document number being used is valid and exists in the system. You can do this by checking the relevant tables or using transaction codes like MB03 to view the document.
  Review Configuration: Check the configuration settings for the material document number ranges in the system. Ensure that they are correctly set up and that there are no gaps or overlaps.
