Which setting must you adjust when setting up a private marketplace deal in AmazonDSP?

When setting up a private marketplace (PMP) deal in Amazon DSP, you must adjust all of the listed settings. You need to specify whether it's a "Preferred deal" or a "Private auction" (not "private deal," which is a common misnomer for PMP deals generally). This distinction impacts how the inventory is offered and priced. You also must select the "Supply source," which identifies the publisher or exchange providing the inventory. Both of these settings are fundamental for defining the parameters and execution of a PMP deal, ensuring the correct inventory is targeted under the agreed-upon terms.
