Transfer Order: Item Shipped but Don't Have in Picking List.

Hi All,

I have a situation here, where we have shipped a transfer order.

We notice there is 1 item which was not picked in picking list but somehow its been shipped.

This is the transfer order, where item highlighted was not picked

This is the picking list, where item 232588 was not in the picking list.

Somehow, the item was shipped in the shipment

I have no idea how this is happening, Appreciate anyone who has experience in this to advise why this happening?

Thanks
