• What is the cause and solution for SAP error message SD_CDS_PROJECTION006 - Value of AccessControl annotation in view &1 different in base view &2 ?

  The SAP error message SD_CDS_PROJECTION006 indicates that there is a mismatch in the AccessControl annotation between a projection view and its underlying base view in the context of Core Data Services (CDS) in SAP. This typically occurs when the access control settings defined in the projection view do not align with those defined in the base view.
  Cause:
  
  Mismatched Access Control Annotations: The AccessControl annotation in the projection view is set differently than in the base view. This can happen if the projection view is trying to enforce different access rights than those defined in the base view.
  Inconsistent Authorization: If the projection view is intended to restrict access more than the base view, or vice versa, it can lead to this error.
  Changes in Base View: If the base view's access control settings were modified after the projection view was created, it may lead to inconsistencies.
  
  Solution:
  
  
  Align Access Control Annotations: Ensure that the AccessControl annotation in the projection view matches that of the base view. You can do this by:
  
  Opening the projection view definition and checking the AccessControl annotation.
  Comparing it with the base view's AccessControl annotation.
  Modifying the projection view to match the base view's settings.
  
  
  
  Review Authorization Requirements: If the projection view needs to have different access control settings, consider whether it is appropriate to create a new base view with the desired access control settings, rather than modifying the existing ones.
  
  
  Rebuild the Projection View: If the issue persists, you may want to recreate the projection view to ensure that it correctly inherits the access control settings from the base view.
  
  
  Check for Updates: If you are using a version of SAP that is subject to updates, check if there are any patches or updates that address this issue.
