Hey party peeps, I'm having trouble setting a shipping method on an intercompany sales order (with interco framework turned on and setup). When I use the Manage Intercompany Sales Orders to generate the paired sales order it does not populate a ship method (I am selecting it on the po) I get an error on save of "You cannot Change the GL Impact of Intercompany transfer lines" if I try to add the ship method and save. NS Support hasn't been helpful yet.

A you set the default ship method on the subsidiary customer record?
