• What is the cause and solution for SAP error message 3G735 - Function module &1 is already active ?

  The SAP error message 3G735 indicates that a function module is already active, which means that the system is trying to execute a function module that is currently in use or has not been properly released after its last execution. This can occur in various scenarios, such as when multiple processes attempt to call the same function module simultaneously.
  Causes:
  
  Concurrent Execution: The function module is being called by multiple sessions or processes at the same time.
  Long-Running Processes: If a function module takes a long time to execute, it may still be active when another call is made.
  Improper Handling: The function module may not have been released properly after its last execution, leading to it being marked as active.
  Locking Mechanisms: SAP uses locking mechanisms to prevent data inconsistencies, and if a lock is not released, it can lead to this error.
  
  Solutions:
  
  Check Active Sessions: Use transaction codes like SM50 or SM66 to monitor active processes and see if the function module is being executed elsewhere.
  Review Code: Ensure that the function module is designed to handle concurrent calls properly. Consider implementing locking mechanisms or using ENQUEUE and DEQUEUE to manage access.
  Increase Timeout: If the function module is expected to take a long time, consider increasing the timeout settings for the session or process.
  Debugging: If you have access to the code, debug the function module to identify why it remains active longer than expected.
  Transaction Management: Ensure that transactions are properly committed or rolled back to release locks and resources.
  System Restart: In some cases, a system restart may be necessary to clear any lingering active states, but this should be done with caution and typically as a last resort.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific function module you are working with.
  Documentation: Review the documentation for the function module to understand its expected behavior and any limitations regarding concurrent execution.
  Performance Monitoring: Use performance monitoring tools to analyze the execution time and resource usage of the function module.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with your SAP Basis team or SAP support for further assistance.
