Event is not triggered

Hi,

For the Real Estate Contract in tcode RECN, i'm using the BO BUS1505. When I test the BO it works fine. But when I give it in my task and create the RE Contract, the event is not getting triggered. I've done binding and event linkage is also activated. I've checked in Trace also. Nothing is displayed in Trace.

Do anyone know what might be the problem ?
