• What is the cause and solution for SAP error message S4RAP_STICKY001 - Action 'DiscardChanges' was called without sticky session. ?

  The SAP error message S4RAP_STICKY001 Action 'DiscardChanges' was called without sticky session typically occurs in the context of SAP Fiori applications that utilize the RAP (Rapid Application Programming) model. This error indicates that an action was attempted without a proper sticky session being established.
  Cause:
  
  Sticky Session Requirement: The RAP model requires a sticky session to maintain the state of the user interaction. A sticky session ensures that all requests from a user are routed to the same server instance, which is crucial for maintaining the context of the user's session.
  Session Timeout: If the session has timed out or if the user has navigated away from the application and returned, the session may no longer be valid.
  Load Balancer Configuration: If your SAP system is behind a load balancer, it may not be configured to maintain sticky sessions correctly, leading to this error.

  Solution:
  
  Check Session Management: Ensure that the session management is correctly configured in your SAP system. This includes checking the load balancer settings to ensure it supports sticky sessions.
  Re-establish Session: If the session has timed out, the user may need to refresh the application or log in again to establish a new session.
  Review Application Logic: Check the implementation of the RAP service and ensure that actions are being called in the correct context. Make sure that the application logic adheres to the requirements of the RAP model.
  Debugging: Use debugging tools to trace the execution flow and identify where the session is lost or not maintained. This can help pinpoint the exact cause of the error.
  SAP Notes and Documentation: Check for any relevant SAP Notes or documentation that may provide additional insights or fixes related to this error.
