Configuring profile parameter for a table lock object

[Former Member]

Hi Experts-

I want to set the 'wait time' (_WAIT) parameter as a profile parameter for a table lock object.

I have created a lock object on a ZTable. I lock and unlock this object in exclusive non-cumulative mode through the enqueue and dequeue lock object function modules. These generated FMs are invoked via my custom function module.

My function module will run in the background as a scheduled task in R/3. I execute the Enqueue FM at the start of the FM and keep the table locked until the last step finishes in my FM and then I Dequeue it. I want to have the processing wait and retry the Enqueuring FM at set intervals in case the one run doesn't finish entirely and a new run of this same job kicks off.

Thank you,

- Vik.

Set the wait parameter = 'X'. These means that if it encounters a lock, then it will wait a certain time for the lock to be released. This certain time is a system value set by your basis team. I don't imagine it being a very long time.

  CALL FUNCTION 'ENQUEUE_EZPIPHYINVREF'
       EXPORTING
            MODE_ZPIPHYINVREF = 'E'
            MANDT             = SY-MANDT
            _WAIT             = 'X'.

Hi Vik,

How much time the system has to wait before re-trying to obtain the lock is something that you cannot control.

However, you can specify how many times the re-trial should be made. The profile parameter for that is <b>enque/delay_max</b>.

I inderstand the maximum number of re-trials is set to 5 by default. You can change it to a more tolerable value for your scenario.
