More than one way to skin a cat here. I'd probably just set up a wizard. step 1, choose a practice with an ERD2WEditToOneRelationship that filters the list to only practices with billables that have no invoice. step 2, choose billables form a filtered list for that practice with an ERD2WEditToManyRelationship component. step 3, edit invoice date validate and save accordingly
