Smart SAP Assistant

• What is the cause and solution for SAP error message SD_CDS_PROJECTION005 - Annotation AccessControl not allowed in view &1 as base view &2 has none ?

  The SAP error message SD_CDS_PROJECTION005 indicates that there is an issue with the access control annotations in a Core Data Services (CDS) view. Specifically, the error states that the AccessControl annotation is not allowed in the view because the base view does not have any access control defined.
  Cause:
  
  Missing Access Control Annotations: The base view referenced in the error message does not have the necessary access control annotations defined. In SAP CDS views, access control annotations are used to define who can access the data in the view.
  Incorrect View Definition: The view might be incorrectly defined or might not be intended to have access control.
  Incompatibility: The projection view is trying to apply access control on a base view that does not support it.
  
  Solution:
  
  
  Add Access Control Annotations: 
  
  Check the base view (the one mentioned in the error message) and ensure that it has the appropriate access control annotations defined. You can add annotations like @AccessControl.authorizationCheck to the base view.
  Example:
  @AccessControl.authorizationCheck: #CHECK
  define view Z_Base_View as select from ...
  
  
  
  
  Remove Access Control from Projection View: 
  
  If the base view is not supposed to have access control, you can remove the AccessControl annotation from the projection view that is causing the error.
  
  
  
  Check for Inheritance: 
  
  If the base view is intended to be used in multiple projection views, ensure that all projection views are consistent in their access control definitions.
  
  
  
  Consult Documentation: 
  
  Review the SAP documentation for CDS views and access control to ensure that you are following best practices.
  
  
  
  Testing: 
  
  After making changes, test the views to ensure that the error is resolved and that the access control behaves as expected.
