  Review the Association Definition:
  
  Check the association definition in your CDS view. Ensure that the join condition includes all the key fields of the target entity.
  For example, if the target entity has multiple key fields, all of them must be included in the join condition.
  
  
  
  Modify the Join Condition:
  
  Update the join condition to include all necessary key fields. This may involve adding additional fields to the ON clause of the join.
  
  
  
  Check Key Fields:
  
  Verify the key fields of both the source and target entities. Ensure that they are correctly defined and that the data types match.
  
  
  
  Test the CDS View:
  
  After making the necessary changes, activate the CDS view and test it to ensure that the error is resolved.
