Steve:

In this case, the OE Order has already been entered for the Customer, often time with a number of comment lines.
We do not want to re-enter the Order, nor to enter any additional data in SalesCQ or OE.

This is simply a PO that we know we need to create, except that we want a number of vendors to quote for the business.
Once we hear from our suppliers, we will decide which vendor to send the PO to.
I do not think what you are describing will work in this instance.

What we really need is the ability to copy a PO with the option of changing the Vendor #, and have the Vendor # replicate through all the detail lines.
