We are trying to develop interface with external system to calculate the shipping costs for a delivery. We will establish RFC connection between SAP and External system.
Do we need SAP .NET connector to send and receive data from/to SAP. SAO shouls act as client and external system as server. If we have to use SAP .NET connectore, can anyone explain me the detailed process of using SAP .NET connector and connecting to external system.If there is anyother way without using SAP .NET connector, i.e by using RFC function modules, can you please xplain that process too. What is the program ID for RFC destination in SM59?
I appreciate your help.
