  Use a Different Document:
  
  If the document is indeed needed for another operation, consider using a different document or creating a copy of the existing document to assign to the new operation.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to document management and operation activities for any specific guidelines or restrictions.
