Outbound IDoc with status 18

Hi Friends,

I have a problem in IDoc. It is a outbound idoc of type Ordrs which is generated from PO to create SO.

But the status is showing 18, which is "Trigerring EDI subsystem Ok".

I dont know how to process after this. The sales order has not been created.

Please help to process the Idoc after this. Will there be any subsytem like GENTRAN.

Thank You

Prabhu
