[RMX:WL] Re: Check Function Module - how to stop duplicate WF trigger

Tue Oct 1 11:17:16 EDT 2013

Hi Karsten,

Follow the below steps that would help.

Right now the issue is becuase of triggering the Create event twice for the same document.

Create a function module which is to read the entries from SWWIHEAD table with workflow template number , Task number (Task Number you can say the User decision or the first step in the workflow) and the document number (Workflow Instance). If the entry does already exists the workflow should not trigger for the second time.

Assing this function module as Check Fucntion module in event linkage table (SWETYPV) which can stop the reciver fucntion module to trigger the workflow for the second time.

Thanks,

Prakash S.

Hi Sheldon,
thanks for the hint with the note and especially the SWEC.

Currently we only have set the flag for CREATE in the respective object.
[cid:image001.png at 01CEBE8A.FEA05DD0]

Nevertheless the system issues the event after a change to the PO as well.
What we do is the following.
After the  creation of a purchase requisition of a certain scenario we call a function module which transfers the purch.requistion into a PO using FM 'BAPI_PO_CREATE1'.
For some cases we need to do some adjustments to the just created PO and we do this after the document is available on the database using FM 'BAPI_PO_CHANGE'. Unfortunately the adjustment we need to do is not possible to be set in the initial CREATE step.
And it looks like the 'BAPI_PO_CHANGE' is causing the system to create another BUS2012.RELEASESTEPCREATED event. In my opinion this should not happen according to the setup in SWEC .

Any ideas??

Best regards
Karsten

Hi Karsten,

I believe many of us have encountered this before.  You may need to remove config in Transaction SWEC.
Please review SAP Note 797775, and you can search the internet, for example, "SAP bus2012 releasestepcreated event"

Hi everybody,

I have quite a strange but interesting question I think to the experts in the group.
Due to the pre-processing setup the PO event BUS2012.RELEASESTEPCREATED is issues twice for the same object (same PO) within seconds.
We see no chance to prevent the double triggering of the event and this should not be the discussion here.
What I am looking for is your help on how to implement a Check Function Module to be integrated in the Event Type Linkage.
I would like to determine if there is already an active WF instance available for the current PO number (should be the object key of the event) and if this is the case the event should raise an exception and should not trigger the WF to start.
If possible it might be could to check the WF Number / Receiver Type (WS9…) as well.

As I have limited knowledge on how to implement this and especially on how to check for the active 1st instance of the workflow for the current object, any hint or code snippet is highly appreciated.

Best regards
Karsten
