Hello - I am setting fields mandatory via workflow (CM, Inv, JE, bill, bill credit). It works fine for the item sublist but how do I set it for the expense sublist or on JE lines?

You cannot set field values or make them mandatory via workflow for the expenses or lines sublist Only Items sublist is supported in workflows

AI1. Thank you ! can it be done via scripting?

Yes it can. Or I think I saw a pre built app that does it via workflow

Thank you
