Event is triggered once, but two workflow instances start

Question

Hello all,
I have a workflow that is triggered by the event ISUSWITCHD.Created.
Unfortunately two workflows of the same version start on this event.
This event is triggered only once according to SWEL.
i have already copied the old workflow pattern (deactivated) and created a new pattern. Problem still exists.
There are no double entries in SWETYPV also.
Is this a Basis problem?
Any help is aprreciated,
Bye,
Holger

Answer 1

1. Go to the transcation SWE2 and check whether there is entry for the same workflow two times. If yes then check for what 
    other event the same workflow is being triggered.
    Create a check function module to test what was the actual triggering object.
2. If there is no such entry then check through out the code whether that worlflow is being called through a function module or  
   not. If that is being callde by a function module then the the SWELS cannot trace the triggering of the workflow and the
   workflow will be trigered.
    If such type of entry is still not there means  that the code does not contain any FM that will trigger the workflow then check 
    for it.
3.Go to the transcation PFTC.
   Give the workflow number and choose the workflow template. There you can check wherther any other event is assigned to  
   the workflow. If yes then trace that and deactivate the linkage if it is not required.
Thanks!
