I have a custom item record that gets added to a line field. Is there any way to add a column to the lookup popup box? I need to display a custom description field in addition to the name.
There’s nothing you can do to add an additional column to that standard field.
One solution is to add a scripted field (where you can specify whatever labels you want) and then use that to set your customfield.
I’m not sure I follow. This isn’t the native item field. It’s a custom line field that points to a custom record.
