• What is the cause and solution for SAP error message /BOBF/CONF_CDS096 - [BO check] ETag defined on a non-root entity does not have any effect ?

  The SAP error message /BOBF/CONF_CDS096 [BO check] ETag defined on a non-root entity does not have any effect typically occurs in the context of Business Object Framework (BOF) and Core Data Services (CDS) in SAP. This error indicates that an ETag (Entity Tag) has been defined on a non-root entity in a Business Object, which is not valid because ETags are only applicable to root entities.
  Cause:
  
  ETag Misconfiguration: The ETag is intended to manage concurrency and versioning for entities. If it is defined on a non-root entity, it will not function as expected because ETags are meant to be used at the root level of the Business Object.
  Model Design Issue: The Business Object model may have been designed incorrectly, where the ETag was mistakenly applied to a child or non-root entity.
  
  Solution:
  
  Review the Business Object Model: Check the definition of the Business Object and identify where the ETag has been defined. Ensure that it is only applied to root entities.
  Remove ETag from Non-Root Entities: If you find that the ETag is defined on a non-root entity, remove it from that entity. Ensure that it is only defined on the root entity of the Business Object.
  Rebuild the Business Object: After making changes, you may need to regenerate or rebuild the Business Object to ensure that the changes take effect.
  Test the Changes: After making the necessary adjustments, test the Business Object to ensure that the error no longer occurs and that the ETag functionality works as intended.
