1. If you create PO in store 1, and add order items for both store 1 and 2. When you login store 2, you should only see items for store 2.
2. Looks like you did not check on “Show All Stores” when you added order items. You can order items for both store 1 and 2 while you log in to store 1. And you can choose ship to stores directly or ship to one store and then distribute/transfer to another store. The main difference is PO report to instruct vendor’s shipment. Please send a screenshot or a video (http://www.recordit.co/) by email how do you add items.
