• What is the cause and solution for SAP error message 12311 - Material &1 locked by user &2 => Change in display mode ?

  The SAP error message "12311 Material &1 locked by user &2 => Change in display mode" indicates that the material you are trying to access is currently locked by another user. This typically occurs when another user is editing or processing the material in a transaction that requires exclusive access.
  Cause:
  
  User Lock: Another user is currently editing the material, which prevents you from making changes.
  Transaction in Progress: The material is being processed in a transaction that requires a lock (e.g., creating or changing material master data).
  System Lock: Sometimes, system locks can occur due to background jobs or processes that are running.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, you can wait for the other user to finish their transaction and then try again.
  Check Lock Entries: You can check the lock entries using transaction code SM12. This will show you which user has locked the material. If you have the necessary authorizations, you can delete the lock entry, but this should be done with caution as it may disrupt the other user's work.
  Contact the User: If you identify the user who has locked the material, you can reach out to them to see if they can release the lock or if they are done with their changes.
  Use Display Mode: If you only need to view the material and do not need to make changes, you can switch to display mode. This will allow you to view the material details without needing to unlock it.
