When planning a campaign, a buyer decides to use a pre-curated collection of non-guaranteed inventory from a specific seller. How is the transaction for this collection handled?

In Marketplace , curated seller inventory such as packages and private deals is activated by attaching that inventory to a line item rather than by starting a new negotiation flow. Google states that for packages, central partner deals, and private deals, buyers can assign them to an existing line item or a new line item. Display & Video 360 also defines line item setup to include choosing inventory source(s) from public inventory, deals and auction packages, and grouped deals. That is why the operational step for this pre-curated non-guaranteed collection is to use the deal as the line item’s inventory source. Google Help+1
