Do we require licences(cost) for only using(/Reusing) SAP Fiori UI (UI5 codes) ?
Also if no then , can we use SAP Fiori Application Front end application and use our own Backend exposed REST services and Map to the corresponding controllers which requires the OData ?
If not and it only works with OData then we can probably use a costume web dispatcher which will translate the REST into understandable OData for Fiori Apps ?
Thanks in advance !!!
