• What is the cause and solution for SAP error message SDDL_PARSER_MSG314 - Key field &1 is missing in ON condition of to-parent association ?

  The SAP error message SDDL_PARSER_MSG314 indicates that there is a problem with the definition of an association in your data model, specifically in the context of the SAP Business Application Studio or SAP HANA modeling. The error message states that a key field is missing in the "ON" condition of a "to-parent" association.
  Cause:
  This error typically occurs when you define an association between two entities (e.g., tables or views) in your data model, and the "ON" condition that specifies how these entities are related does not include a key field from the parent entity. In other words, the association is not properly defined because it lacks the necessary key field that uniquely identifies records in the parent entity.
  Solution:
  To resolve this error, you need to ensure that the "ON" condition of your association includes the appropriate key field from the parent entity. Here are the steps to fix the issue:
  
  
  Identify the Parent Entity: Determine which entity is the parent in the association you are defining.
  
  
  Check Key Fields: Review the key fields of the parent entity. You can do this by looking at the entity definition in your data model.
  
  
  Modify the Association: Update the "ON" condition of the association to include the key field from the parent entity. The syntax typically looks like this:
  association to_parent_name: ParentEntity
  on ParentEntity.keyField = ChildEntity.foreignKeyField
  
  
  Validate the Model: After making the changes, validate your data model to ensure that there are no further errors.
  
  
  Test the Association: Once the model is validated, test the association in your application to ensure that it behaves as expected.
  
  
  Related Information:
