OAI Event is not reading the workflow queue

Question

I'm creating the workflow event using iStudio (created automatically by iStudio) with the following information:
Item Type: OAI Process Bundle: EDWARD
Internal Name: I_EDWARD_PAATRANSACTION_OAI_V1
Display Name: Receive Request EDWARD.PAATransaction:IN
Description: OAI Event
Event Action: Receive
Event Filter: oai.edward.paatransaction.oai_v1.receive_request.oai_v1
Cost: 0.0
I also create the event subscription for oracle.apps.wf.event.agent.create, oracle.apps.wf.event.event.create, and oracle.apps.wf.event.subscription.create and put the following information:
System: WFLOWDEV.MAXIMUSBC.CA
Source Type: External
Event Filter: oracle.apps.wf.event.subscription.create
Source Agent: <blank>
Phase: 1
Status: Enabled
Rule Data: Key
Rule Function: WF_EVENT_FUNCTIONS_PKG.RECEIVE
Workflow Item Type: EDWARD
Workflow Process Name: PAATRANSACTION
Out Agent: <blank>
To Agent: [email protected]
Priority: Normal
Parameters: <blank>
I can see that the interconnect OAI Hub is putting a message into the WF_IN queue but the event does not dequeue the message and run the process.
So, I don't know if I'm missing anything here or there is something wrong with my configuration.
Can anyone help me please?
Thanks,
Edward

Edward,
I am basing this reply on the OAI build I have on my laptop, which is an Oracle 9iAS Integration build, however I do not think that it has changed since.
Before you do this, it is always a good idea to add the "OAIHeader" objects to the Common View.
1. Under "Common Views", expand the "Business Objects" and find your Business Object (e.g. MY_BO)
2. Under the "Events", expand the "Events" to find your event (e.g. MY_EVENT)
3. Highlight you event (MY_EVENT), Right-click on your mouse, and choose "Edit". This will bring up the "Edit Event" window.
4. Choose "Add". This will create a new line.
The 'Name' will be blank.
The 'Type' will be "String".
The 'Owner' will be blank.
The 'Array' will be blank, and
The 'Default' will be 'NULL'.
5. On the 'Type' value ("String"), click on the value "String". This will bring up a pop-up list.
6. From this list, select "Data Type..."
7. Now click once anywhere in the "Edit Event" window. This will bring up a "Common Data Types" window.
8. Scroll down, find and highlight the the name "OAIHeader". Press 'OK'
9. Now back in the 'Edit Event' window, you will notice that the type is "OAIHeader".
10. Now give the "Name" (currently still blank) a value. Give it the name "OAIHeader" too.
11. Press 'OK'
12. You will now see that the Event now has "OAIHeader" information. Some of these values will be of interest and of use later.
The actual values for "EventName, EventVersion" etc. will be added to the data of the message at Runtime.
*** TIP: I always do the above exercise first for every Business Object event I create. Once I've included the 'OAIHeader', I then add all of the actual other message attributes to the message afterwards. ***
Create Content Based Routing Rules
In this example, I am going to route a message from a sending DB Adapter (DBAPP1) to the Workflow Adapter (WORKFLOW). Then once the message has been passed to the Workflow, it will be passed to the receiving DB Adapter (DBAPP2).
1. In iStudio, under the "Design" tab, expand the "Enabling Infrastructure".
2. Under "Content Based Routing", find your Business Object.
e.g. MY_BO
3. Expand the Business Object, and then expand the "Events" to find your event.
e.g. MY_EVENT
4. On the Event (MY_EVENT), highlight it, then right mouse click. Choose Edit.
5. A window will pop-up called "Content Based Routing: MY_EVENT"
6. Hit the "New" button.
7. Expand the message structure (MY_EVENT), and find the 'OAIHeader' node.
8. Expand the "OAIHeader" node, and select (highlight) the "SendingApplication" attribute.
9. Press 'Next'. This will move you onto the next screen.
10. From the drop-down list, choose the "==" Operator. Press 'Next'.
11. Enter a Value in the box. Since my sending application is "DBAPP1", type in "DBAPP1". Press Next.
12. Since I have completed the "source" CBR rules, check the "Condition Complete" radio button, and Press 'Next'.
13. Now in the next screen, select "WORKFLOW". Now press 'Finish'.
Perform the same as above, this time routing the message from the "WORKFLOW" adapter to your receiving adapter (e.g. 'DBAPP2'). If the Workflow message does not have the 'OAIHeader' information in it's structure, once again refer to the above and add it in.
Once you have completed all of your CBR configuration, use "File > Push Metadata" to send this new message structure and CBR rules to your adapters (DBAPP1, WORKFLOW and DBAPP2).
HTH,
Yan
