• What is the cause and solution for SAP error message SDDL_PARSER_MSG460 - Key field "&1" missing in On condition of association "&2" ?

  The SAP error message SDDL_PARSER_MSG460 indicates that there is a problem with the definition of an association in your data model, specifically in the context of the SAP HANA database or the SAP Business Technology Platform (BTP). This error occurs when a key field that is expected in the "ON" condition of an association is missing.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Missing Key Field: The key field specified in the association's "ON" condition is not present in the associated entity or table.
  Incorrect Association Definition: The association may be incorrectly defined, leading to a mismatch between the expected key fields and the actual fields present in the entities.
  Model Changes: If there have been recent changes to the data model, such as renaming or removing fields, it could lead to this error.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check the Association Definition:
  
  Open the data model where the association is defined.
  Verify the "ON" condition of the association and ensure that the key field specified (represented by &1) is correctly defined and exists in the associated entity (represented by &2).
  
  
  
  Verify Key Fields:
  
  Ensure that the key field is indeed a key in the associated entity. If it has been renamed or removed, you will need to update the association accordingly.
  
  
  
  Update the Data Model:
  
  If the key field is missing, you may need to add it back to the entity or adjust the association to use a different key field that exists in both entities.
  
  
  
  Rebuild the Model:
  
  After making changes, rebuild or activate the data model to ensure that the changes take effect.
  
  
  
  Test the Association:
  
  After resolving the issue, test the association to ensure that it works as expected without generating any errors.
