While testing the Picking and Receiving feature in POS for a demo, the Purchase Order that I had created in Dynamics AX 2012 does not display in POS.
I have created a Purchase Order line using the Site and Warehouse for my store.
When I log into POS and click on Picking and Receiving, the PO does not show up in the Picking\Receiving window.
What I have found is that in Dynamics AX, the Purchase Order does not have the Site and Warehouse set in the Header. I have a blank Site and Warehouse because I do not have a default set on my Vendor. POS looks for the Site and Warehouse in the Header of the PO.
Once the Site and Warehouse is set onthe PO header, I can now see the PO in POS.
