Sales Order Web Service creation

Hi all,

I want to use a WS to update Sales orders from SAP Business One into C4C.

I couldn't find relevant WS in the API lIst (recent order doesn't give enough information since I want order lines too)

so, I want to create a new WS using the SDK for Sales Orders, however, there is no BO for Sales Orders.

I checked the Repository Explorer and learned that Sales Orders are actually Sales Quote with Type Code of 2059.

So, my question is: How can i define a new WS for Sales Orders?

Thanks,

Dror
