• What is the cause and solution for SAP error message /SAPAPO/OM_UPGRADE030 - &1 started in parallel session, therefore display only ?

  The SAP error message /SAPAPO/OM_UPGRADE030 typically indicates that a certain operation or transaction in the SAP Advanced Planning and Optimization (APO) module is being executed in parallel sessions. This can happen when multiple users or processes attempt to access or modify the same data simultaneously, leading to potential conflicts or data integrity issues.
  Cause:
  
  Parallel Sessions: The error occurs when the same transaction is initiated in multiple sessions. SAP restricts certain operations to ensure data consistency and integrity.
  Long-Running Processes: If a long-running process is still active, and another user tries to start the same process, this error may be triggered.
  Locking Mechanism: SAP uses a locking mechanism to prevent data corruption. If a session is already processing a request, subsequent requests will be restricted.
  
  Solution:
  
  Check Active Sessions: Identify and check the active sessions that are running the same transaction. You can use transaction codes like SM50 (Process Overview) or SM66 (Global Process Overview) to monitor active processes.
  Wait for Completion: If another session is processing the same transaction, wait for it to complete before trying again.
  Terminate Unnecessary Sessions: If you find that there are unnecessary or stuck sessions, you may need to terminate them (with caution) using transaction SM50 or SM66.
  Review User Access: Ensure that users are not inadvertently starting the same transaction multiple times. Educate users on the proper usage of the system to avoid conflicts.
  System Configuration: In some cases, it may be necessary to review system configurations or settings that could be causing excessive parallel processing.
