  The SAP error message EH2030, which states "No objects available; installed devices are currently locked," typically occurs in the context of SAP's Environment, Health, and Safety (EHS) module or when dealing with device management in SAP. This error indicates that the system is unable to access certain objects or devices because they are currently locked, possibly due to ongoing processes or transactions.
  Causes:
  
  Locked Devices: The devices or objects you are trying to access are currently locked by another user or process. This can happen if another transaction is being processed that involves the same devices.
  User Permissions: The user may not have the necessary permissions to access the devices or objects.

  Solutions:
  
  
  Check for Locks: 
  
  Use transaction code SM12 to check for any locks on the devices or objects. You can see which user or process is holding the lock and take appropriate action (e.g., wait for the process to complete or contact the user).
  
  
  
  Release Locks: 
  
  If you have the necessary permissions, you can release the locks from SM12. However, be cautious when doing this, as it may disrupt ongoing processes.
  
  
  
  User Permissions: 
  
  Verify that the user has the appropriate authorizations to access the devices. You may need to consult with your SAP security team to ensure that the user roles are correctly assigned.
