• What is the cause and solution for SAP error message 00798 - Ticket contains different ABAP user ID (Re-Authentization) ?

  The SAP error message "00798: Ticket contains different ABAP user ID (Re-Authentication)" typically occurs in scenarios where there is a mismatch between the user ID associated with a session or ticket and the user ID that is currently logged in or being used to access the system. This can happen in various contexts, such as when using SAP GUI, web applications, or during remote function calls (RFC).
  Cause:
  
  Session Mismatch: The user session may have been established with one user ID, and then an attempt is made to perform an action with a different user ID.
  Security Policies: SAP systems often have security policies that require re-authentication if there is a change in user context or if the session has been idle for a certain period.
  Single Sign-On (SSO) Issues: If SSO is configured, there may be issues with the ticketing mechanism that leads to a mismatch in user IDs.
  Transport Layer Security: If there are issues with the transport layer or if the user is trying to access a different client or system, it may trigger this error.
  
  Solution:
  
  Re-Authenticate: The simplest solution is to log out and log back in with the correct user ID. This will refresh the session and ensure that the user ID matches.
  Check User Context: Ensure that the user context is consistent throughout the session. If you are switching users or contexts, make sure to properly log out of the previous session.
  Review SSO Configuration: If using SSO, check the configuration to ensure that the tickets are being generated correctly and that there are no issues with the identity provider.
  Clear Cache: Sometimes, clearing the cache of the SAP GUI or web browser can resolve session-related issues.
  Check Security Settings: Review the security settings in the SAP system to ensure that they are not overly restrictive or misconfigured.
  Consult Basis Team: If the issue persists, it may be necessary to consult with the SAP Basis team to investigate any underlying issues with the system configuration or user management.
