• What is the cause and solution for SAP error message PPE_INST023 - Geometric instance &1/&2 currently being processed by &3 ?

  The SAP error message PPE_INST023 indicates that a geometric instance (such as a part or component in a product structure) is currently being processed by another transaction or user. This typically occurs in the context of Product Lifecycle Management (PLM) or Production Planning (PP) modules, where multiple users or processes may attempt to access or modify the same geometric instance simultaneously.
  Cause:
  
  Concurrent Access: Another user or process is currently working on the same geometric instance, leading to a lock on that instance.
  Long-Running Transactions: A transaction that takes a long time to complete may hold the lock longer than expected.
  System Configuration: The system may be configured in a way that allows for locking conflicts, especially in environments with high user concurrency.
  
  Solution:
  
  Wait and Retry: If the instance is being processed by another user, you may need to wait until that user completes their transaction. You can then retry your action.
  Identify the Lock: Use transaction codes like SM12 (to view locks) or SM21 (to check system logs) to identify which user or process is holding the lock on the geometric instance.
  Contact the User: If you identify the user who is holding the lock, you can contact them to see if they can complete their transaction or release the lock.
  System Administrator Intervention: If the lock persists and is causing significant issues, a system administrator may need to intervene to release the lock or investigate further.
  Review System Performance: If this error occurs frequently, it may be worth reviewing system performance and user access patterns to optimize how geometric instances are handled.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as PPEM (for managing engineering change management) and PPEM1 (for managing product structures).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Training: Ensure that users are trained on how to properly manage geometric instances and understand the implications of concurrent access.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with SAP support for further assistance.
