I don't have SAP ERP system, but S/4HANA 1511.
I would like to create a demo apps (Approve Purchase Order), but this app is not available on S/4HANA, so I can't extend it.
But there is a demo app (Project from sample application), my question:
-. have some experts out there ever used this?
-. could you explain how I can link it to the back-end? (I am using SAP WebIDE)
-. If there is still no idea related to questions above, is there any fiori app related to approval purchase order for my system? (my inbox seems not working)
Thanks in Advance.
