Client ABAP Proxy : how to know which program is calling that service interface proxy

Hi All,

I have prepared some client proxy in ECC to communicate with PI.

But, if I am not wrong, unlike server proxy which is written directly in the class Provider class in SPROXT transaction, in client proxy we write abap code to trigger proxy in SE38 .

My question is : If I am in SPROXY and looking at any outbound SI, of which proxy is already generated, then how can in SE38  can I find which program is triggering that interface or proxy?
