Trigger the abap proxy in custom FM

Hi Experts,

I have a requirement to trigger abap proxy through my custom function module. I need to send the populated structure to SAP PI using ABAP Proxy.

Note - ABAP Proxy details are provided from SAP PI. Function Module logic is to be written inside the ABAP Proxy.

Can you please tel me how I can meet this requirement?

Thanks and regards,

Jasvinder Kumar
