Whats the best way to add a new column to the Line Items in a Transfer Order? I need to show the Quantity On Hand, for the selected Location, for every product in the Transfer Order.

Customize > New Column Field. Source > Item, Source From > On Hand.

Thanks @Nicholas Cole but that gives me the data from all locations, not only the To Location of the current Transfer Order

@Edgar Valdés on your Custom transfer form, have you considered the native column for On Hand.

We need the column for the Role that approves the T.O., to check the requested quantities against the stock for the given warehouse. We can compare with external tools, Excel, two tabs in NetSuite, etc. but I'm looking for a single screen with both data, to ease the process. Am I missing something obvious?

Must be a config difference. I'm looking at a TO now, and see when I look at a native On Hand field which I have added to my Transfer Order form that it is dynamic values based upon the (send) Location.

Weird... I will look into it. Thanks @Netsuite Tragic
