BTP Feedback

So we are using SAP Business Technology Platform (BTP) for a use case which is of Supplier Portal where once the supplier is onboarded they are gonna track their invoices , their primary data , they can raise new invoices , they can edit there existing primary data stored with us and then that data is given to SAP MDG where the workflows are triggered and upon successful completion the confirmation is sent back to SAP Business Technology Platform(BTP). For this we are also using SAP BUILD Workzone where we are creating a new SITE for the suppliers and are using SAP Fiori as the Fiori technology (using SAP UI Integration cards)
