Add field to be copied for intercompany order

We added a custom field to our sales order form–“Attention”. This field needs to be copied along with all other information if the order is designated Intercompany.

Currently, if someone fills that field in and designates the order “Intercompany”, everything else is copied over except that field. We need that field due to address validation issues with our sales tax component.

Let me know if you need any other information from me. Thanks!

where it has to get copied?
