INTER COMPNY

HI ALL

i hv a doubt in intercompany process

suppose i hav 3 company codes

one in US, Canada,SA

n suppose if sales org of US wants to get stock frm Canada plant we need to define a customer in Canada n assign it to US sales org.

my doubt is if i wud like to do intercompany with SA ALSO HOW WILL I DO IT

we can assign only one customer number to a sales org in intercompany rite??

plz clarify wether intercompany is only between 2 company codes ?

cant we do it between more than 3 company codes

plz share ur ideas............
