Unable to get ICPO to show intercompany PO

Good Day

I have been following the Multi-Site document for the process of intercompany. However I cannot get the PO from the Sales (Custopmer) company to show on the selling (Supplying) company via the ICPO form. I have run both the Multi-Company direct server process on both sides and they both have run. Any reasons why this is occurring?
