  The SAP error message EG178, which states "Command group &1 is already being used - change not possible," typically occurs when you attempt to modify a command group that is currently in use or locked by another process. This can happen in various scenarios, such as when a user is executing a transaction that utilizes the command group, or if there are background jobs or other processes that are currently accessing it.
  Causes:
  
  Active Sessions: The command group is being used in an active session by another user or process.
  Background Jobs: A background job is currently executing a task that involves the command group.
  Locking Mechanism: SAP uses a locking mechanism to prevent changes to objects that are currently in use, which can lead to this error.
  Transport Requests: If the command group is part of a transport request that is being processed, it may also lead to this error.
  
  Solutions:
  
  Check Active Sessions: Use transaction code SM04 to check for active user sessions. If you find a session using the command group, you may need to wait until it is completed or contact the user to close it.

  Wait and Retry: If the command group is temporarily locked, waiting for a few moments and then retrying the operation may resolve the issue.
  Check Transport Requests: If the command group is part of a transport request, ensure that the transport is not currently being processed. You can check this in transaction SE09 or SE10.
