• What is the cause and solution for SAP error message ESH_ENG_CDS_ABAP021 - Required @EnterpriseSearch.enabled is not annotated ?

  The SAP error message ESH_ENG_CDS_ABAP021 Required @EnterpriseSearch.enabled is not annotated typically occurs in the context of SAP's Enterprise Search functionality, particularly when working with Core Data Services (CDS) views. This error indicates that a required annotation for enabling Enterprise Search on a CDS view is missing.
  Cause:
  The error arises when a CDS view that is intended to be used for Enterprise Search does not have the necessary annotation @EnterpriseSearch.enabled. This annotation is essential for the SAP system to recognize that the CDS view should be included in the Enterprise Search framework.
  Solution:
  To resolve this error, you need to annotate the relevant CDS view with the @EnterpriseSearch.enabled annotation. Here’s how you can do that:
  
  
  Open the CDS View: Access the ABAP Development Tools (ADT) in Eclipse or the relevant transaction in the SAP GUI where the CDS view is defined.
  
  
  Edit the CDS View: Locate the CDS view that is causing the error and open it for editing.
  
  
  Add the Annotation: At the top of the CDS view definition, add the following line:
  @EnterpriseSearch.enabled: true
  Your CDS view definition should look something like this:
  @AbapCatalog.sqlViewName: 'YOUR_SQL_VIEW_NAME'
  @AbapCatalog.compiler.compareFilter: true
  @EnterpriseSearch.enabled: true
  define view YOUR_CDS_VIEW_NAME as select from YOUR_TABLE
  {
      // Your fields here
  }
  
  
  Activate the CDS View: After adding the annotation, activate the CDS view to apply the changes.
  
  
  Re-test the Enterprise Search: Once the CDS view is activated with the correct annotation, re-test the Enterprise Search functionality to ensure that the error is resolved.
  
  
  Related Information:
  
  Enterprise Search: This is a feature in SAP that allows users to search across various data sources in a unified manner. It leverages CDS views to provide a rich search experience.

  Annotations: Annotations in CDS views provide additional metadata that can influence how the view is processed and utilized by various SAP applications, including Enterprise Search.
  
  If you continue to experience issues after adding the annotation, ensure that there are no other underlying problems with the CDS view or the Enterprise Search configuration in your SAP system.
