• What is the cause and solution for SAP error message /IWBEP/CM_V4S_RUN018 - The too old frontend system does not support stateful session handling ?

  The SAP error message /IWBEP/CM_V4S_RUN018 indicates that the frontend system you are using is too old to support stateful session handling in the context of SAP Gateway or OData services. This typically occurs when there is a mismatch between the versions of the frontend and backend systems, particularly when the frontend system does not support the required features for stateful sessions.
  Cause:
  
  Version Mismatch: The frontend system (like SAP Fiori or SAP UI5) is running an older version that does not support the stateful session handling feature introduced in later versions of SAP Gateway or OData services.
  Configuration Issues: The configuration settings for the OData service or the SAP Gateway might not be set up correctly to handle stateful sessions.
  Browser Compatibility: Sometimes, the browser being used may not support the necessary features for stateful session handling.
  
  Solution:
  
  Upgrade Frontend System: The most straightforward solution is to upgrade the frontend system to a version that supports stateful session handling. Check the compatibility matrix for the versions of SAP Gateway and the frontend system you are using.
  Check Configuration: Review the configuration settings for the OData service in the SAP Gateway. Ensure that the service is configured to support stateful sessions if required.
  Use Stateless Sessions: If upgrading is not feasible, consider modifying the application to use stateless session handling instead. This may involve changes in how the application manages user sessions and state.
  Browser Update: Ensure that you are using a modern and supported web browser. Update the browser to the latest version if necessary.
