Credit checking on IMT routed via OM

If to to org is linked to an internal customer so that it populates on sales order when IMT is routed via OM ... will we be able to trigger credit checking (either the on submit as well as the line level DOO task added before shipping)?

Nowhere can I find information on this that confirms or denies this ability.

I guess when IMT is within a BU, it would be very difficult, as there is no invoicing and hence what would be the credit exposure? But even if it crosses BU's and one configures IC Invoicing ... would that account into credit exposure and support credit checking at all?
