@al3xicon I have Assemblies that are Special Work Order Items and as soon as you put them on a Sales Order the: Create WO column check box become checked automatically(on that line). As far as I know your special work order item is the top most one in the hierarchy meaning if I have a component of the Assembly being a Special Work order Item that would not trigger the action of Create WO, which mean in your case your kit need to be the Special Work Order Item or you will need an script to create a WO for you member assembly...
