When ever I am creating sales order line, the subinventory column of oe_order_lines_all is null and I could not find in the form where I can manually input it. Where can I default the subinventory? Where can I manually input it in the form?
I already have tried that several times but it always give me the message "There are no additional fields to show for this region". And when I'm going through the fields on Shipping tab, Subinventory is not there.
You'll always get the "There are no additional fields to show for this region" message when you try to add fields with your cursor in the first field. As the user above mentioned, you have to navigate out of that first field to add a column via folder options.
