If you use responsibility centers to administer your business, you can assign responsibility centers to your vendors. When you assign a responsibility center a vendor, all purchases made from this vendor will by default be administered by this responsibility center.
Open the Vendor Card window.
Select the vendor you want to assign a responsibility center to.
On the General tab, in the Responsibility Center field, select the responsibility center you want the vendor to be linked to.
