  Wait for Completion: If another user or process is currently working on the installation, you may need to wait until they complete their transaction.
  Release Locks: If you have the necessary authorizations, you can manually release locks using transaction SM12. However, be cautious when doing this, as it may lead to data inconsistencies if the other process is still running.
  Check for Open Work Items: Use transaction codes like IW38 or IW39 to check for open work orders or tasks related to the installation. Resolve or complete these tasks if possible.
