You can change the view that is returned in the dropdown to include company and then grab it.
We only have one company but here is what I did for ship to address in SOA. I added the ship to number to the end of the dropdown with a pipe delimiter and then parse off to use in ECM. The
then to get the shiptonum field I do this calculation.
SPLITGETREV(FT_SHIP_TO_DESC, "|", 0)
I made a sample view in the IDC database with company in the name and Vend_Comp value field
