Looking to stop sending IDOC if output has been already processed for PO

Question

Hi,
I am using the Message type ORDERS to trigger the IDOC for the purchase order based on the output type. But my requirment is that if the output is already processed for a  specfic purchase order then it should not allow to process the output again for that purchase order. So i am writing a logic in user exit that if NAST table entry is already exist and proccessed for the output type for specfic purchase order then i want to stop sending the idoc.  As NAST entries doesn't contains any segment data due to that i am unable to set the ALE filter in BD64 transtaction .So could you please anyone give me any suggestion how can i stop sending the IDOC if output has been already proceessed  so that it will helpful for me.
Thanks in advance for your help .
Regards,
Kiran

1. In case you intend to use maintain runtime then use a single receiver and add multiple inbound interfaces. This is the easiest solution
2. use a BPM. use send steps in serial. First send step should be File (request for acknowledgment) and then followed by send step for mail.
Do not go for scripts etc unless no other solution persists since maintenance and support in the future will always be an issue.
let me know if u still have issues.
