Smart SAP Assistant

• What is the cause and solution for SAP error message START_MESSAGES034 - Test plan is under execution in other instance. ?

  The SAP error message "START_MESSAGES034 Test plan is under execution in other instance" typically occurs when you attempt to execute a test plan that is already being processed in another session or instance of SAP. This is a common issue in environments where multiple users or processes may be trying to access the same test plan simultaneously.
  Cause:
  
  Concurrent Execution: The test plan is currently being executed by another user or process, which locks the test plan for exclusive access.
  Session Management: If a previous session did not close properly or is still active, it may hold a lock on the test plan.
  System Configuration: Certain configurations in the SAP system may restrict concurrent executions of test plans.
  
  Solution:
  
  
  Check Active Sessions: Verify if another user or session is currently executing the test plan. You can do this by checking transaction codes like SM50 (Process Overview) or SM66 (Global Work Process Overview) to see if the test plan is being executed elsewhere.
  
  
  Wait and Retry: If another session is using the test plan, wait for it to complete and then try executing the test plan again.
  
  
  Terminate Stuck Sessions: If you find a session that is stuck or not responding, you may need to terminate it. This can be done through transaction SM50 or SM66, but be cautious as terminating sessions can lead to data loss or corruption.
  
  
  Check Locks: Use transaction SM12 to check for any locks on the test plan. If you find locks that are no longer needed, you can delete them, but ensure that you understand the implications of doing so.
  
  
  Review Configuration: If this issue occurs frequently, review the configuration settings related to test plan execution to see if adjustments can be made to allow for concurrent executions.
  
  
  Consult Documentation: Refer to SAP documentation or support for specific guidelines related to your version of SAP, as there may be version-specific considerations.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM50, SM66, SM12, and ST22 (for dumps) to help diagnose and resolve issues.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Permissions: Ensure that users have the appropriate permissions to execute test plans, as permission issues can sometimes lead to unexpected behavior.
