WF_EVENT.Raise() is not triggering the event subscription

Hi,

I have created business event that has a subscription which calls the plsql function to insert the data in a custom table. When I test this event from the Business Events screen from workflow manager it is working and inserting the data. But when I raise this event from plsql code from sqldeveloper seems like not working. No error. The subscription is not executed. Some suggested to put commit statement after WF_EVENT.RAISE() function. Still not working. Seems little bit wierd to me. Any other suggestions?

By the way apps version is 12.1.3.

Thanks!!
