Explanation
A purchasing organization is an organizational unit that is responsible for procuring materials or services for one or more plants and negotiating prices and conditions with vendors. When defining purchasing organizations, you must consider the following aspects:
Each purchasing organization has its own info records, which contain information about the conditions and delivery data for a material from a specific vendor.
Each purchasing organization has its own supplier master data, which contain information about the general data, accounting data, and purchasing data for a supplier. References: SAP S/4HANA Sourcing and Procurement | SAP Learning, Course S4500, Unit 1, Lesson 1.
