• What is the cause and solution for SAP error message STC_TM397 - Execution of a new task list run in same work process rejected ?

  The SAP error message STC_TM397 indicates that the execution of a new task list run in the same work process has been rejected. This typically occurs in the context of background processing in SAP, particularly when using the SAP Task Manager (STC) for managing task lists.
  Cause:
  The error can be caused by several factors, including:
  
  
  Work Process Limitation: The work process is already busy executing another task list or job, and SAP does not allow multiple task lists to run in the same work process simultaneously.
  
  
  Configuration Issues: There may be configuration settings that limit the number of concurrent task list executions.
  
  
  System Load: High system load or resource contention can lead to the rejection of new task list executions.
  
  
  Task List Status: The task list may be in a status that does not allow it to be executed again until the current execution is completed.
  
  
  Solution:
  To resolve the STC_TM397 error, you can take the following steps:
  
  
  Check Work Process Status:
  
  Use transaction code SM50 to monitor the work processes. Check if the work process is busy with another task. If so, wait for it to complete.
  
  
  
  Review Task List Execution:
  
  Check the status of the task list you are trying to execute. Use transaction STC01 to view the task list and its execution history. Ensure that it is not already running.
  
  
  
  Adjust Configuration:
  
  If necessary, review the configuration settings for task list execution in the SAP system. You may need to adjust the maximum number of concurrent executions allowed.
  
  
  
  Increase Resources:
  
  If the system is under heavy load, consider increasing the resources available to the SAP system, such as CPU or memory, to improve performance.
  
  
  
  Retry Execution:
  
  After ensuring that the work process is free and the task list is in a suitable state, retry executing the task list.
  
  
  
  Check Logs:
  
  Review the system logs (transaction SM21) and the developer traces (transaction ST22) for any additional error messages or information that could provide more context about the issue.
