• What is the cause and solution for SAP error message AMDP_CMP_CHECKS001 - The CDS SESSION CLIENT in method &1 was changed from "&2" to "&3" ?

  The SAP error message AMDP_CMP_CHECKS001 indicates that there is a discrepancy in the client context when executing an ABAP Managed Database Procedure (AMDP) that uses Core Data Services (CDS). Specifically, it means that the client session was changed during the execution of the method, which can lead to inconsistencies in data access and processing.
  Cause:
  The error occurs when:
  
  The CDS view or AMDP method is executed in a different client than the one it was originally intended for. This can happen if the session context is altered, for example, by switching clients or if the method is called in a way that changes the client context.
  The method is trying to access data that is client-dependent, and the client context does not match the expected client.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Client Context: Ensure that the client context remains consistent throughout the execution of the AMDP method. Verify that the client you are working in is the same as the one expected by the CDS view or AMDP.
  
  
  Review AMDP Calls: If the AMDP method is being called from different clients or contexts, ensure that the calls are made in a consistent manner. Avoid switching clients during the execution of the method.
  
  
  Use Client-Independent Logic: If possible, modify the logic in the AMDP or CDS view to be client-independent, or ensure that it handles client-specific data correctly.
  
  
  Debugging: Use debugging tools to trace the execution of the AMDP method and identify where the client context is changing. This can help pinpoint the exact location or condition that leads to the error.
  
  
  Check Authorization: Ensure that the user executing the AMDP has the necessary authorizations for the client being accessed.
  
  
  Consult Documentation: Review SAP documentation or notes related to AMDP and CDS to see if there are any specific guidelines or known issues related to client handling.

  AMDP (ABAP Managed Database Procedures): A feature in ABAP that allows you to write database procedures in ABAP and execute them directly in the database.
  CDS (Core Data Services): A framework for defining and consuming semantically rich data models in SAP systems.
  Client Concept in SAP: SAP systems are multi-client, meaning that data can be segregated by client. Each client has its own set of data, and certain operations may be client-dependent.
