Unique situation of requring theeceipt of direct ship order at mill before onward to cusotmer-INDIRE

Cross docking may seem like a direct fit but our requirment is a bit more complicated. currently we have a customisation in place which will convert line type D on the purchase order to S so that they can be receipted into the mill.

Is there some other workaround possible using standard JD Edwards finctionality?

thanks
