Documentation
Definition
A lock can have one or two owners (enqueue owners) Accordingly, a transaction contains two lock owners. One of the lock owners is passed to the update task when the update is called. The other lock owner remains in the transaction.
A lock owner is represented by a system-wide unique key. This key contains, among other information, the time when it is assigned.
Lock owner keys are assigned as follows:
- When you start a transaction or a report, both lock owner keys are assigned.
- When the update is called (COMMIT WORK after CALL FUNCTION IN UPDATE TASK), a lock owner key is assigned to replace the lock owner key passed to the update.
- On your return after branching to transactions and reports (CALL TRANSACTION, SUBMIT), the lock owner keys of the calling transaction are valid again.
When a lock operation is called, the parameter "_SCOPE" specifies the lock owner the operation is for.
_SCOPE = 1 : for the owner remaining in the transaction
_SCOPE = 2 : for the owner passed to the update task
_SCOPE = 3 : for both owners
For more information see the documentation on enqueue and the update process.
