Submit Custom Report in PO Approval Process

Question

Hi All,
We use R12, our requirment is to submit a custom report when PO is approved.
Not in all cases we need this. when user select 'Approve' option for a Manually created PO,
and in the Approval form, when the User selects 'Email' check box and approves it.
Irrespective of value that is given in email field, when that Email check box is checked and PO is approved, then the custom report should get submitted.
For this our funtional team is requesting to copy the PO approval Workflow and write a event there.
But I feel this can be achived in much easier way. But not getting any ideas.
Can anyone let me know what could be the best and effective way than modifying Workflow.
thanks

Answer 1

1) Write an alert on po_action_history insert and fire the conc. proram if the conditions are satisfied
2) Write a custom pl/sql procedure that looks at all POs that are approved in the last x minutes and for each appropriate po, submit the conc. program using fnd_request.submit_request. Then schedule a run of this pl/sql procedure by creating a conc. program for it.
Hope this helps,
