SADL_GW_DT_CDS011 - Details

• The SAP error message SADL_GW_DT_CDS011 indicates that there is a missing annotation @ObjectModel.semanticKey in your Core Data Services (CDS) view definition. This annotation is required when you are working with UUID-based models in SAP, as it specifies which field(s) in your data model should be treated as the semantic key.
  
  Cause:
  The error occurs because:
  
  You are using a UUID-based model, which requires a semantic key to uniquely identify records.
  The CDS view that you are trying to use does not have the @ObjectModel.semanticKey annotation defined for the appropriate field(s).

  To resolve this error, you need to add the @ObjectModel.semanticKey annotation to your CDS view definition. Here’s how you can do it:
  
  
  Identify the UUID Field: Determine which field in your CDS view should be treated as the semantic key. This is typically the UUID field.
  
  
  Modify the CDS View: Add the @ObjectModel.semanticKey annotation to the identified field. Here’s an example of how to do this:
