Unit Retail on Purchase Orders

We are using Oracle Retail 13.1 however this may apply to all release 13.

The ORDLOC table has a unit_retail column which is populated from the current unit retail and updated by RPM.  However this mechanism does not allow for situations where the planned unit_retail on receipt of the PO is different to the current unit_retail and items are ticketed by the supplier.

For example I have an item with current unit_retail of $20.00 and raise a PO for delivery in 3 months time.  At that time I plan to have the unit_retail of this stock at $25.00  It is ticketed by the supplier and therefore the ticketing information must be available to the supplier before shipment.
