We are developing a Fiori App with side-by-side extension option for our S/4HANA Cloud system. We want to have single-sign-on for our new build Fiori app. We are using two APIs Purchase order (scenario SAP_COM_0053), Material Document (Scenario SAP_COM_0108). Purchase Order API support OAuth2 whereas Material document doesn’t support OAuth2. Material document only support Basic, x509.
Is it possible to create a Fiori app with single-sign-on features with x509 Authentication Methods?
Do we need to create two separate SAP BTP Destination one with OAuth2 for Purchase Order and another with x509 for Material document for our Fiori App ?
