is there a way to get the response of a web service from DS

Hello,

I have a HR dashboard on which I want to show employee photos.

Normally, in HR ecc system HRWPC_RFC_EP_READ_PHOTO_URI function is used to get URL of the picture.

I can run this function from DS side via a web service; but how can I get the response of the web service?

I hope I'm clear.

Thanks.
