In S/4HANA, users no longer see transactions but Fiori apps. Behind every app there is a simple chain: a table, a CDS view that makes it readable, an OData service that exposes it, a user interface generated by Fiori Elements, and behavior written with RAP. Extensions, for their part, increasingly go to the SAP BTP platform to keep the core clean. This module follows a single piece of data from end to end: the purchase orders of SENTINEL SA.
