• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK376 - Foreign Key Association &1 in CDS View &2 contains not only elements ?

  The SAP error message CFD_REGISTRY_CHECK376 indicates that there is an issue with the foreign key association in a Core Data Services (CDS) view. Specifically, it suggests that the foreign key association defined in the CDS view contains elements that are not solely foreign key fields. This can lead to inconsistencies and issues when trying to activate or use the CDS view.
  Cause:
  The error typically arises from one of the following scenarios:
  
  Mixed Elements: The foreign key association is defined in such a way that it includes both foreign key fields and other fields that do not belong to the foreign key relationship.
  Incorrect Association Definition: The association might be incorrectly defined in the CDS view, leading to a violation of the expected structure for foreign key associations.
  Modeling Errors: There may be errors in the way the underlying tables or views are modeled, causing the foreign key association to reference non-key fields.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the CDS View Definition:
  
  Check the definition of the foreign key association in the CDS view. Ensure that it only includes fields that are part of the foreign key relationship.
  The association should only reference the key fields of the target entity.
  
  
  
  Modify the Association:
  
  If you find that non-key fields are included in the association, modify the association to include only the relevant key fields.
  Example:
  define association to target_entity as association_name
    on target_entity.key_field = source_entity.foreign_key_field
  
  
  
  
  Check Underlying Data Model:
  
  Ensure that the underlying tables or views are correctly defined and that the foreign key relationships are properly established in the database.
  
  
  
  Activate the CDS View:
  
  After making the necessary changes, try to activate the CDS view again. If the changes are correct, the error should be resolved.
  
  
  
  Consult Documentation:
