  Correct Data Entry: If the error is due to incorrect data entry, correct the entries to ensure that assignment numbers are only applied to valid line types.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on assignment numbers and line types for the document you are working with.
