Data Provide implementation for RFC in SAP nw gateway web service using SEGW

Hello Everyone,

I am new to SAP net weaver gateway web service implementation.

I have written a function module on SAP R/3 system and want to call this function from SAP Netweaver Gateway system. This function will return a table and i want to pass this table to web service.The connection between two systems is tested and there in no problem with the connection.

I have created a project using t-code SEGW.

I have created Entity types and Entity set and have generated the service.

Now I am not clear how to call this remote function(which returns a table) from methods DPC_EXT/ DPC and what should be the syntax for the same?

I have done further steps like registering service and testing the web service (OData) for local database values but not for the remote database values.So please help for implementation of RFC call .
