ALECTC Check Event Alert Should Fail All the Time

Hello,

I do not know much about event alerts, because we only have one, and I do not have a working one to compare it to.

We have a concurrent request, PO_ACTION_HISTORY (Check Event Alert), that fails for Signal 11.

I would expect to be able to find an Alert Definition named PO_ACTION_HISTORY, but cannot find this alert.  Should this alert be there, or do I misunderstand how this works?

If this alert should be there, then how come it does not fail all the time?  Occassionally, the concurrent request returns successful.  How can that be?

Thank you,
