  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their processing. Once they are done, you should be able to access the key figure schema without issues.
  Check Active Sessions: If you have multiple sessions open, check if you are already processing the key figure schema in another session. Close any unnecessary sessions.
  Contact the User: If you know who the other user is, you can contact them to see if they can finish their processing or release the lock.
  System Administration: If the issue persists and you believe it is a system error, you may need to contact your SAP Basis or system administrator. They can check for any locks in the system and release them if necessary.
  Transaction Monitoring: Use transaction codes like SM12 (to check for locks) and SM21 (to check system logs) to monitor and troubleshoot the issue further.
