Smart SAP Assistant

• What is the cause and solution for SAP error message /PLMI/PPE_INST_TRANS015 - Instance transfer from &1 to &2 not possible, change number &3 is locked ?

  The SAP error message /PLMI/PPE_INST_TRANS015 indicates that an instance transfer from one location to another is not possible because the specified change number is locked. This typically occurs in the context of SAP's Project Management or Logistics modules, where change numbers are used to manage and track changes to project instances or materials.
  Cause:
  
  
  Change Number Locking: The change number associated with the instance transfer is locked, which means that it is currently being used or modified by another user or process. This can happen if:
  
  Another user is editing or processing the change number.
  A background job is currently using the change number.
  The change number is in a status that does not allow modifications (e.g., released or completed).
  
  
  
  Authorization Issues: The user may not have the necessary authorizations to perform actions on the locked change number.
  
  
  Solution:
  
  
  Check Lock Status:
  
  Use transaction code SM12 to check for locks on the change number. You can search for the specific change number to see if it is locked and by whom.
  If you find that the change number is locked by another user, you may need to wait until they release it or contact them to resolve the issue.
  
  
  
  Release the Lock:
  
  If you have the necessary authorizations and determine that the lock is no longer needed, you can manually delete the lock entry in SM12. However, this should be done with caution and typically only if you are sure that the lock is not being used by another legitimate process.
  
  
  
  Check Change Number Status:
  
  Ensure that the change number is in a status that allows for instance transfers. If it is in a status that prevents changes, you may need to change its status or create a new change number.
  
  
  
  User Authorization:
  
  Verify that you have the necessary authorizations to work with the change number. If not, contact your SAP security administrator to obtain the required permissions.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team for specific guidelines related to your organization's use of change numbers and instance transfers.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (for lock entries), SE11 (for data dictionary), and SE37 (for function modules) that may help in troubleshooting.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Forums: Consider visiting SAP community forums or support channels for additional insights and solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
