Documentation
Definition
Cross-VM locks are used within the VM Container to synchronize global data. To minimize collisions there are various locks for the individual application areas, and you can tell these locks apart by their names.
This field specifies the name of the lock. You can see whether the VM has just requested the lock, or whether the lock is already in the critical section in the column "Status" on the initial screen in SM52. After the lock has been requested, the status is "Wants to lock". In the critical section the status is "Running", and in the column " Info" you can see the lock icon.
