• What is the cause and solution for SAP error message /SAPAPO/SCC351 - User & already processing transportation lane ?

  The SAP error message /SAPAPO/SCC351 User & already processing transportation lane typically occurs in the SAP Advanced Planning and Optimization (APO) module when a user attempts to access or process a transportation lane that is already being processed by another user. This is a concurrency control mechanism to prevent data inconsistencies and conflicts.
  Cause:
  
  Concurrent Access: Another user is currently processing the same transportation lane, which locks the lane for editing or processing.
  Session Issues: The user may have multiple sessions open, and one of them is already processing the transportation lane.
  System Configuration: The system may have specific configurations that restrict access to certain objects when they are being processed.
  
  Solution:
  
  Wait and Retry: If another user is processing the transportation lane, wait for them to complete their task and then try again.
  Check Active Sessions: Ensure that you do not have multiple sessions open that might be accessing the same transportation lane. Close any unnecessary sessions.
  Identify the User: If you have access to system logs or monitoring tools, identify which user is currently processing the transportation lane and coordinate with them.
  Lock Release: If you believe the lock is no longer valid (e.g., the user has logged off unexpectedly), you may need to contact your system administrator to release the lock.
  System Configuration Review: If this issue occurs frequently, review the system configuration and user access settings to ensure they align with your business processes.
