For the system to automatically convert a purchase requisition (PR) into a purchase order (PO), several master data and transactional data prerequisites must be met. First, both the material master record (plant-specific purchasing view) and the business partner master record (purchasing data) must have the "Automatic Purchase Order" indicator set. This flags both the item and the supplier as eligible for this automated process. Second, the purchase requisition itself must have a unique and valid source of supply assigned to it. This source, typically a purchasing info record or a contract, provides the necessary information, such as the vendor and valid pricing conditions, that the system needs to create the purchase order document without manual intervention.

A. A contract with plant-specific conditions exists for the material and the vendor.

This is too specific. A purchasing info record is also a valid source of supply, so a contract is not a mandatory prerequisite.

E. A plant-specific source list entry exists for the material.

While a source list is a primary tool for automatic source determination, the direct prerequisite for PO conversion is that a source is assigned to the PR, which is stated more accurately in option D.
