Oracle workflow Events

Question

I have defined a process which is executed on receiving a predefined event. When I raise the event using the web interface provided with the software, the event is raised, and the corresponding workflow is executed. But, when I try to raise the same event, using a 'Raise Event' activity within another process, it does not work. It just shows the steps : Start -> Raise Event -> End as 'Complete', though the Raise Event step does not trigger off the event. Please help as soon as possible !
Thanks and Regards,

Answer 1

This error message means that the subscription was found and executed, and it tried to send the event to the workflow process, but
it could not do so because there was no activity in the process that was able to receive the event. If the process begins with the
Receive event activity marked as a Start activity, that activity can only receive the event if the process has not been started yet,
i.e., that item type/item key combination does not exist yet. If that item type and item key have already been used, Oracle Workflow
cannot start another process with the same item type and item key and you will get this error.
When a subscription sends an event to a process, it uses the correlation ID in the event message as the item key for the process, or
the event key if no correlation ID is defined. What you need to do is provide a value, either using the correlation ID or the event key,
that has not been used as an item key for this item type before.
Or else (which may be simpler) put the process that raises the event and the process that receives the event in different item types.
Then it will be easier to make sure the item type/item key combination is unique and has not been used before.

Thank you for the response !
I am enclosing the notification message I found below. It says something like a subscription is not found to the event 'oracle.apps.wf.event.any'. But, if that is the case, then could you tell me how the same wks when I raise the same event through the web interface ie. the defined subscription works and the corresponding workflow executes ! Is there anything else need to be set up when we have the processes that raise the evnt and that receive the event,respectively ,under the same item type ?
The message that I found in the Notifications list is :
