eSupplier PO visibility and Consignment PO's

Good morning,

We are on PS 9.1 and use both eSupplier and Consignment.I wondered if anyone uses both and if they had run into issues with Supplier Purchase Order Acknowledgements- the Supplier changing pricies, qty, etc. on a PO.

I wondered if anyone had customized to show that the item and/or PO is consignment related through the Supplier Portal Pages, on the POA the buyer accepts/rejects, and/or on the PO line? I know that you can see the item is consigned, but it's buried in the distribution.

There doesn't seem to be a good way to see that information- an Icon or indicator would be good- really on both sides of the fence- for the Supplier and for the Buyer accepting the POA- even an icon on the PO itself would be good.  It would also be good if the PO could not be updated/acknowledged by the Supplier. Price, Qty, Lead time,etc... Consignment is so touchy... this will be a big deal if Supplier's are acknowledging PO's with changes.
