Why I am getting message when I am not using anything associated with it ?

Hi Guys,

I am working on Gap Analysis for the problem associated during outbound delivery transaction i.e VL02N.

When we enter the name of delivery document in VL02N and then go to Environment -> Document flow, I get a message at the bottom saying "NO RFC destination defined for small parcel carrier Purolator".

Now, I guess generally this message is associated when you are using XSI i.e Exchange Shipping Interface (Generally used to connect to UPS and FEDEX)

But in my company we are not using XSI because we are using XI.

So what is the reason I am getting that message associated with XSI?

Inputs will be highly appreciated...
