If I have a formula text case statement in result column in a saved search, can I get the id of a field instead of text?

@battk Thats what I thought, but it didn't work. It is a custom column on the record that comes from a list

what does your Transaction Line Field setup page look like

Not sure if this is what you are asking, but it a a transaction line field which is sourced from a list.

Give me enough information to create the field myself
