Which organizational assignment must NOT be maintained when setting up a cross-company-code purchasing organization?

When configuring a cross-company-code purchasing organization, the assignment that does not need to be maintained is the company code to purchasing organization assignment. A cross-company-code purchasing organization is designed to carry out procurement activities across different company codes, meaning it operates independently of individual company codes. This allows for a consolidated purchasing process that can leverage volume discounts and optimize procurement strategies across various entities.

In this context, maintaining a company code to purchasing organization assignment would be counterintuitive, as the purpose of a cross-company-code purchasing organization is to facilitate procurement activities that span multiple company codes. Thus, there is no requirement to link specific company codes to the purchasing organization in this setup.

In contrast, maintaining the plant to purchasing organization, purchasing group to purchasing organization, and storage location to purchasing organization assignments is crucial for operational purposes, as these elements define where goods will be delivered, who is responsible for purchasing activities, and how inventory is managed in a cross-company environment.
