<font size=2 face="sans-serif">One other thing to consider - if the two
events are being generated in a very short timeframe, and you're using
the event queue to deliver the event, you may wish to revise using the
event queue (if you get low volumes of these events), or look at the event
queue table if Susan's check on a workflow existence fails (just to ensure
there's not one in the queue waiting to be created). Not sure if
there's a WAPI to check this, but it's table SWEQUEUE for reference.</font>

<br><font size=2 color=#004080 face="Calibri">After the creation
of a purchase requisition of a certain scenario we call a function module

<br><font size=2 color=#004080 face="Calibri">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.</font>
<br><font size=2 color=#004080 face="Calibri">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 .</font>

Hi everybody,<br>
<br>
I have quite a strange but interesting question I think to the experts
in the group.<br>
Due to the pre-processing setup the PO event BUS2012.RELEASESTEPCREATED
is issues twice for the same object (same PO) within seconds.<br>
We see no chance to prevent the double triggering of the event and this
should not be the discussion here.<br>
What I am looking for is your help on how to implement a Check Function
Module to be integrated in the Event Type Linkage.<br>
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.<br>
If possible it might be could to check the WF Number / Receiver Type (WS9…)
as well.<br>
<br>
As I have limited knowledge on how to implement this and especially on
how to check for the active 1<sup>st</sup> instance of the workflow for
the current object, any hint or code snippet is highly appreciated.<br>
<br>
Best regards<br>
Karsten<br>
