How To Fix ESH_ENG_CDSVAL_ES006 - '@ObjectModel.semanticKey' must be annotated at view

SAP Error Message - Details

• Message type: E = Error

• Message number: 006

• Message text: '@ObjectModel.semanticKey' must be annotated at view

What causes this issue?

The usually highly denormalized search-views need a key definition that
reduces the cartesian product defined by the view as such to the entity
that is actually to be found. For this purpose, annotation
@ObjectModel.semanticKey (to be annotated at the view-level) is used.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Define the actual entity key by annotation @ObjectModel.semanticKey.

• What is the cause and solution for SAP error message ESH_ENG_CDSVAL_ES006 - '@ObjectModel.semanticKey' must be annotated at view ?

  The SAP error message ESH_ENG_CDSVAL_ES006 '@ObjectModel.semanticKey' must be annotated at view typically occurs in the context of Core Data Services (CDS) views in SAP. This error indicates that the CDS view you are working with is missing a required annotation that defines the semantic key for the view.
  Cause:
  The error arises because the CDS view is expected to have a semantic key defined using the @ObjectModel.semanticKey annotation. This annotation is crucial for identifying the key fields of the CDS view, which are used for various purposes, including data retrieval and integration with other SAP components.
  Solution:
  To resolve this error, you need to add the @ObjectModel.semanticKey annotation to your CDS view. Here’s how you can do that:
  
  
  Open the CDS View: Access the CDS view in the ABAP Development Tools (ADT) or the relevant development environment.
  
  
  Identify Key Fields: Determine which fields in your CDS view should be considered as the semantic key. These are typically the fields that uniquely identify a record in the context of the view.
  
  
  Add the Annotation: Modify the CDS view definition to include the @ObjectModel.semanticKey annotation. Here’s an example of how to do this:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AbapCatalog.compiler.compareFilter: true
  @ObjectModel.semanticKey: ['Field1', 'Field2']  // Replace with your actual key fields
  define view Z_MY_CDS_VIEW as select from my_table
  {
      key Field1,
      key Field2,
      Field3,
      Field4
  }
  In this example, Field1 and Field2 are defined as the semantic key fields.
  
  
  Activate the CDS View: After making the changes, activate the CDS view to apply the new annotation.
  
  
  Test the View: Once activated, test the CDS view to ensure that the error is resolved and that it behaves as expected.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework for defining semantically rich data models in SAP. CDS views can be used for reporting, analytics, and data integration.
  Annotations: Annotations in CDS views provide metadata that can influence how the view is processed and consumed by various SAP applications.
  SAP Documentation: For more detailed information on CDS views and annotations, refer to the official SAP documentation or the SAP Help Portal.
  
  By following these steps, you should be able to resolve the error and successfully define the semantic key for your CDS view.
