  Define Key Field:
  
  If you are developing or modifying a function module, make sure to include a key field in the export parameters. This could be a primary key from the database table or a unique identifier relevant to the data being processed.
  
  
  
  Review Data Model:
  
  If the error is related to a data model, ensure that the model includes a key field. You may need to adjust the data structure to include a unique identifier.
