SAP C4C (Cloud for Customer) Online/offline App Mode capabilities for Pricing

I have a very important question that I need to solve ASAP.

We are implement C4C for sales reps on the road and they will be using the mobile app for sales orders.

Does C4C mobile app (ONLINE mode) supports all the pricing procedures integration with ERP or does it only support the standard pricing PR00?

If not? How can the sales rep execute a sales order on his mobile app with all the needed functionalities?

Will he have to log into the web C4C url?

What are the limitations of c4c sales mobile app, I was not able to find this specific information?

Please let me know,

Very much appreciated.
