• What is the cause and solution for SAP error message CM_SUB_INFOSYS016 - User &1 is already processing &2 &3 ?

  The SAP error message CM_SUB_INFOSYS016 indicates that a user is already processing a specific task or transaction in the system. The message typically includes placeholders for the user ID and the specific task or transaction being processed, which are represented as &1, &2, and &3.
  Cause:
  This error usually occurs when:
  
  A user attempts to start a new session or transaction that is already being processed by the same user.
  The system has a lock mechanism in place to prevent multiple instances of the same transaction from being executed simultaneously by the same user.
  There may be a long-running process that has not yet completed, causing the system to block further attempts to initiate the same process.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Active Sessions:
  
  Use transaction code SM04 to check the active sessions for the user. Look for any sessions that are currently processing the same task.
  If you find an active session that is stuck or not responding, you may need to terminate it.
  
  
  
  Wait for Completion:
  
  If the task is still processing, you may need to wait for it to complete before attempting to start it again.
  
  
  
  Log Off and Log Back In:
  
  Sometimes, simply logging off and logging back into the system can clear any session locks.
  
  
  
  Contact System Administrator:
  
  If you are unable to resolve the issue, contact your SAP system administrator. They can check for any locks in the system and may need to release them.
  
  
  
  Review System Logs:
  
  Check the system logs for any additional information that might indicate why the user is locked out of the transaction.
