Rerouting 855 PO confimation to File System

Hi XI community,

I have a 855 PO Confirmation getting into my SRM(EBD) system.

Now I want to reroute it to a file system instead of overloading my EBD system.

I am using PurchaseOrderRequest data type

Can anyboy help me on how to handle the reusability in this case.

Do I have to create a another msg equal to PurchaseOrderRequest and proceed from there?.

That is a long msg though!

Please advise .

Thanks
