I created a PO, entered many SKUs, received the goods and all goods are there except 1, SMD LED Blue. They are the only item with 0 stock for some reason. I've checked and that SKU has:
1. It is present in the confirmed PO, with qty 3.
2. It is present in inventory but with qty 0.
3. It has no purchase history from the product form.
How should I fix that?
