Error: Not all reservations could be blocked

Message No. M7545

Solution: You can check whether the Reservation is opened in change mode or not. If yes, you can come out of the reservation so that it will work.

This happens if the Reservation is locked by another user. You can check with SM12 transaction code to find the lock.

You will get the lock entries. You can remove username and run to see all the locks as you are not aware about the user who locked it.
