Calling RFC from custom connector

Hi,

I am developing a custom connector for UWL to get tasks from 3rd party system.

I need to call a RFC from backend SAP system to complete Input data for this 3rd party provider.

I assume that I have to make an RFC call from getItems() method of connector.

Any idea how to call a RFC from UWL custom connector code?

Please help.

Thanks & Regards,

Amey
