Buyer Purchasing Class (PO04.2)
Use Buyer Purchasing Class (PO04.2) to assign major and minor purchasing classes to a buyer. Using this form is optional. You can use it if you decide to limit a buyer you have set up in PO04.1 (Buyer) to order from specific major and/or minor purchasing classes only. The buyer is then restricted to ordering only the classes of items entered here.
Processing Effect
If a buyer creates a purchase order that includes an item or items that are not in the purchasing classes assigned to that buyer, the purchase order cannot be released in PO20.1 (Purchase Order Entry), it must be released in PO22.1 (Authorization, Release) by someone authorized to do so. Use IC07 (Purchasing Class) to define purchasing classes. You can also use the IC11.1 (Item Master) to assign purchasing classes to individual items.
