SAP Lock (Enqueue Lock)

[Former Member]

Hi there,

I have used SAP Enqueue and Dequeue Lock in my program. However, it does not seems to work. Do I need to have a specific authorisation in order to be able to perform Enqueuing n Dequeuing?

In addition, when i perform CALL FUNCTION 'ENQUEUE_XXXXXX', what does the return code, sy-subrc = 4 signifies?

Thank You.

For sy-subrc = 4 U need to check the Exceptions declared in FM

'ENQUEUE_XXXXXX' .

check 4th exception in the FM ..

locking failed if sy-subrc = 4. Check your function module exceptions and see what fourth exception is. maybe object is already locked and you can't lock it again.

Use transaction SM12 to see if you already have any locks. Also worth checking the data you are trying to lock is actually on your database table.
