Intercompany Drop Ship Order

We have a prospect that has two companies, one base in ROI and one based the UK. The 2nd ROI company does not hold any stock and all sales orders are supplied by the primary UK company. 

We’ve worked through using intercompany and believe it would work for them to a degree but ideally we would like the Intercompany Sales Order in the UK company to be dispatched to the customer address for the ROI company. 

If we select to raise the intercompany PO from the ROI company to the UK company as a drop ship PO, we cannot seem to generate the intercompany SO from the “Generate Intercompany Sales Orders” process within the UK company. 

This means the ROI company would have to theoretically “Receipt” the stock to their ROI warehouse to immediately despatch their customer sales order. This adds another level of admin the customer would like to avoid as they would like the paperwork from the UK company to have to delivery address of the ROI company customer. 

Any suggestions would be appreciated.
