Service procurement involves creating a purchase order (PO) and service entry sheet (SES). The PO is created using transaction code ME21N, with account assignment categories and item category of "D" for services. Detailed service lines are entered in the item details/services tab. The SES is then created using transaction code ML81N, by entering the relevant PO number. The SES captures additional details for procurement and billing of the services.
