• 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
