• What is the cause and solution for SAP error message /SAPAPO/PDRP_APPR032 - Planning lock changed ?

  The SAP error message /SAPAPO/PDRP_APPR032 indicates that a planning lock has changed during the execution of a planning process in SAP Advanced Planning and Optimization (APO). This typically occurs when multiple users or processes are trying to access or modify the same planning data simultaneously, leading to a conflict in the planning lock.
  Cause:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same planning object (e.g., a planning book, data view, or key figure) at the same time.
  Lock Timeout: A lock may have been held for too long, causing another process to attempt to access the same data, resulting in a lock change.
  System Configuration: Incorrect configuration of the planning area or planning book settings may lead to unexpected lock behavior.
  
  Solution:
  
  Retry the Operation: Often, simply retrying the operation after a short wait can resolve the issue, especially if it was caused by a temporary lock.
  Check for Active Sessions: Use transaction codes like SM12 to check for active locks in the system. Identify and resolve any unnecessary locks held by other users or processes.
  Review User Access: Ensure that users have the appropriate access rights and that there are no conflicting processes running simultaneously.
  Adjust Lock Settings: If the issue persists, consider reviewing and adjusting the lock settings in the system configuration to minimize conflicts.
  Batch Processing: If applicable, schedule batch jobs during off-peak hours to reduce the likelihood of concurrent access issues.
  Consult SAP Notes: Check for any relevant SAP Notes or updates that may address known issues related to planning locks.
