Logical database & is already being edited by &

What causes this issue?

The logical database you specified is already being edited by another
user. Therefore, you can access it only in display mode.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check that you are not already editing the logical database in another
mode and, if necessary, switch to that mode.
If another user is editing the logical data base, wait until he/she has
finished. Usually, the lock is set only for a short time.
If you cannot wait, contact the user whose name is displayed in this
message.
