  Review Data Source:
  
  If the model is based on a data source (like an InfoProvider), check the data source to ensure it has key fields defined.
  If necessary, modify the data source to include key fields.
  
  
  
  Re-activate the Model:
  
  After making changes, you may need to re-activate the model to ensure that the changes take effect.
