When there is a demand for certain products, there are three possible ways in which this demand can be fulfilled. They can all lead to an inbound process with a goods receipt that needs to be posted in the SAP S/4HANA system. Products are either purchased from an external supplier, produced in their own plant, or procured internally from another plant within the company structure. So, procurement can either be internally or externally. Frequently, certain products are always produced in-house or purchased externally. This can be specified in the material master of these products using a field called the procurement type.

Depending on the way of procurement that is selected in a certain situation, a purchase order, a production order or a stock transport order is created in the SAP S/4HANA system.
