Question about pricing in Purchase Orders

Dear all,

Currently for intercompany replenishment flow we are using the P vendors, the problem is every day there are more plants that can be a P vendor and we have to upload several times the prices one per P vendor.

My question is the following:

Is it possible to upload the price at the G vendor and when we place the Purchase Order to the P vendor the price will come up from the G vendor?

Which setting or transaction I should use?

Thanks in advance,

Regards,

Antonio
