According to the PMBOK Guide, Plan Procurements is the planning process whose explicit outputs and purpose include documenting project purchasing decisions, specifying the procurement approach, and identifying potential sellers - the question's description is a verbatim match to this process's definition. It occurs before any seller engagement, distinguishing it from the later Conduct and Administer processes.

Administer Procurements involves managing active procurement relationships and monitoring contract performance after a contract has already been awarded.

Close Procurements involves formally completing and settling each project contract and occurs at the end of the procurement lifecycle.

Conduct Procurements involves obtaining seller responses, evaluating bids, selecting a seller, and awarding a contract - activities that follow planning.
