is it possible in a client script to set a expense line sublist field as mandatory? It's one that isn't available to set as mandatory in the workflow. I'm thinking getCurrentSublistField with .isMandatory = true; , but it seems to not be working

We have a workflow action that can do this in short order

'set mandatory fields' workflow action doesn't seem to have an option for 'expmediaitem' (attachment), or 'memo' fiels on the expense line level, that's what you're referring to. But maybe I could set a condition to remove the submit button unless they are populated....

Expense sublist is not available to a workflow out of the box

Oh, got it.... workflow action script..... nuff said actually! THanks Jeffery!

Of course you can
