RF Gun to Fiori

Hello,

I am new to Fiori.

We run goods receipt application using RF Guns

We need to get a good upgrade option so next processes that we need to put on RF Gun could be put on more sophisticated screens like Fiori instead of continuing with RF Gun.

I understand that if I do get an existing application in Fiori on Goods Receipt (or whatever new process I want to implement) then I can use it or tweak it at field or screen level using enhancements. (may be using River RDE)

but if I do not get existing Fiori app for my process then I need to create on SAP UI5.

we dont have anything on Fiori in our system.

is this approach correct to stat with?

thanks

bhakti
