Procurement groups
Each company is assigned to one and only one procurement group. Multiple companies can be assigned to the same procurement group. The procurement group assignment for a company makes all vendors and buyers assigned to the procurement group available for that company, and any other companies assigned to the same procurement group. Also, contracts can be established for a procurement group so that the contract can be used by more than one company.
A procurement group can have more than one company, but each company is only assigned to one procurement group.
