• What is the cause and solution for SAP error message /CFG/ACTIVATION133 - Simulation: Changes are not saved! ?

  The SAP error message /CFG/ACTIVATION133 with the description "Simulation: Changes are not saved!" typically occurs in the context of configuration changes in the SAP system, particularly when working with the Customizing Implementation Guide (IMG) or during the activation of certain configuration settings.
  Cause:
  
  Simulation Mode: The error indicates that the system is in simulation mode, which means that any changes made during this session will not be saved. This is often used for testing purposes to see the effects of changes without committing them to the system.
  Authorization Issues: The user may not have the necessary authorizations to save changes in the configuration.
  Technical Issues: There may be underlying technical issues, such as system locks or database problems, preventing changes from being saved.
  
  Solution:
  
  Exit Simulation Mode: If you are in simulation mode, exit this mode and perform the changes in the actual configuration mode. Look for an option to switch from simulation to actual configuration.
  Check Authorizations: Ensure that you have the necessary authorizations to make and save changes in the configuration. You may need to contact your SAP security administrator to verify your roles and permissions.
  Review Configuration Steps: Make sure you are following the correct steps for the configuration changes. Sometimes, specific prerequisites must be met before changes can be saved.
  Check for Locks: Investigate if there are any locks on the configuration tables that might be preventing changes from being saved. You can use transaction codes like SM12 to check for locks.
  Consult Logs: Check the system logs (transaction SLG1) for any additional error messages or warnings that might provide more context about the issue.
  System Restart: In some cases, a system restart or a refresh of the session may resolve temporary issues.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SPRO (for accessing the IMG), SM12 (for checking locks), and SLG1 (for viewing logs).
