IDOC-File Can Partner Type be KU or LI ?

Hi All

I am sending IDOC from R/3 system to XI.

Can partner type for XI be LI or KU?

What my assumption is, whenever R/3 sends IDOC to XI, it treats XI as LS always. So partner profile configured for XI will be under partner type LS

Please correct me if I have any misconcept.

Thanks in Advance.
