• What is the cause and solution for SAP error message /PM0/FPP023 - Run is being read (exit 1400): &1 ?

  The SAP error message /PM0/FPP023 Run is being read (exit 1400): &1 typically occurs in the context of the SAP Production Planning (PP) module, particularly when dealing with production orders or planning runs. This error indicates that a specific run is currently being processed or read, which prevents further actions on it until the current operation is completed.
  Cause:
  
  Concurrent Processing: The error often arises when multiple users or processes are trying to access or modify the same planning run or production order simultaneously.
  Long-Running Processes: If a planning run is taking longer than expected, it may lead to this error as the system locks the run for processing.
  System Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a run is locked by another transaction, you will encounter this error.
  
  Solution:
  
  Wait and Retry: If the error is due to concurrent processing, waiting for a few moments and then retrying the operation may resolve the issue.
  Check for Active Sessions: Use transaction codes like SM12 to check for any active locks on the run. If you find a lock that is no longer needed, you can delete it (ensure you have the necessary authorizations and that it is safe to do so).
  Monitor Long-Running Jobs: Use transaction SM37 to monitor background jobs. If a job is taking too long, you may need to investigate why it is delayed.
  Consult with Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to check for any underlying system issues or to release locks that are not being cleared automatically.
  Review Custom Code: If there are any custom developments or enhancements in your SAP system that interact with the planning runs, review them to ensure they are not causing the issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM37 (to monitor jobs), and SE11 (to check table definitions).
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Review SAP documentation related to the Production Planning module for best practices and guidelines on managing planning runs and production orders.
