DAX HELP

So if i understand correctly you want the sum of order quantity and the sum of invoiced quantity, but dont count the invoiced quantity if order quantity is empty?

If this is the case you can make a measure something like this, could be a little off as i have no sample data:

for OrderQuantity you can just do
