Event queue - not a problem, just well... strangeness

[Sue Doughty]

Hi Michael,

I just tried the same event with the invalid key and the event delivered properly.  When the workflow that was triggered started, it went into error status because the trip did not exist.

Do you have the Event trace turned on?  If not, turn it on (SWELS for that specific event) long enough for your event to be triggered again.  When you look in the Event trace in SWEQADM, you can double click the event that you had the issue with and in the Receiver Data section you will see if there were any error messages.

There could be an issue in the Workflow's Header section under Start Events that is not allowing the workflow to start.

Regards,
Sue

Wuggers,

Here is an issue which has probably been discussed before, but I cannot seem to find an answer for it.

With a few of our workflows, we use the event queue.  And of course the background job (SWEQSRV - running program RSWEQSRV) dequeues the events and triggers the workflows.  I think most people here are familiar with this process.

The wierd thing is, if I have an event in the queue (which I think is actually table SWEQUEUE) with an invalid key (in my case BUS2089-CREATED with key whatever - 999999999999999999, when the job runs, it will create a new event with key 000000000000000000 of the same object and event.  This new event also has an invalid key, and so will keep generating a new event with each run of the batch job (the events do not stack up, it just removes the old one and replaces it with a new event).

Is this normal behavior for this program?  Can this behavior be changed (maybe to not generate a new event)?  Any similar experiences?
