• What is the cause and solution for SAP error message T1520 - Risk hierarchy locked by another user; save not possible ?

  The SAP error message T1520, which states "Risk hierarchy locked by another user; save not possible," typically occurs in the context of SAP GRC (Governance, Risk, and Compliance) when a user attempts to modify or save a risk hierarchy that is currently being edited or locked by another user. This locking mechanism is in place to prevent data inconsistencies and ensure that changes are made in a controlled manner.
  Cause:
  
  Concurrent Access: Another user is currently editing the risk hierarchy, which locks the hierarchy for other users.
  Session Timeout: A previous session may not have released the lock properly due to a timeout or unexpected termination.
  System Configuration: The system may have specific configurations that enforce locking mechanisms more strictly.
  
  Solution:
  
  Wait and Retry: If another user is editing the hierarchy, you may need to wait until they finish and release the lock. You can check with your team to see if someone is currently working on it.
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can look for locks related to the risk hierarchy and see if you can identify the user who has locked it.
  Release Locks: If you have the necessary authorizations, you can manually delete the lock entries in SM12. However, this should be done with caution and ideally after confirming with the user who holds the lock.
  Contact Administrator: If you are unable to resolve the issue, contact your SAP system administrator or GRC support team for assistance. They can help identify the user holding the lock and may be able to release it if necessary.
  Review System Settings: If this issue occurs frequently, it may be worth reviewing the system settings and configurations related to locking mechanisms to ensure they are appropriate for your organization's needs.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to view and manage lock entries) and SU01 (to manage user profiles).
  User Communication: Establish a communication protocol among users who work with the risk hierarchy to minimize concurrent editing.
  Documentation: Ensure that there is proper documentation and training for users on how to handle risk hierarchies to avoid locking issues.
  
  By following these steps, you should be able to address the T1520 error and continue working with the risk hierarchy in SAP.
