• Key Concepts: 
  CDS access control is a feature of the ABAP Runtime Environment (BC-ABA) in SAP that allows users to control access to CDS views. CDS views are data models that are used to define and access data from multiple sources. Access control is used to ensure that only authorized users can access the data in the CDS view. 
  
  How to use it: 
  To use CDS access control, users must first create a CDS view and then define the access control rules for the view. The access control rules can be defined using the ABAP language or using the graphical user interface (GUI). Once the access control rules have been defined, users can then grant or deny access to the CDS view based on the rules. 
  
  Tips & Tricks: 
  When creating access control rules for a CDS view, it is important to consider who should have access to the data in the view. It is also important to consider what type of access should be granted or denied. For example, some users may only need read-only access while others may need full read/write access.
