I guess Yes.Have you tried it?
Do not define an event alert on the table FND_CONCURRENT_REQUESTS. Oracle Alert submits a concurrent request to the concurrent manager when an event alert is triggered by an insert or update to an event table. For concurrent processing to occur, every submitted concurrent request automatically gets inserted as a row in the
FND_CONCURRENT_REQUESTS table. If you define an event alert on this table, you create a situation where the event alert will cause an exception to occur recursively.
