I attached a solution. I put "Factory Work Order" and "Parts Produced" as dimensions in the row shelf. I also added Sum(Number of Records) in the row shef but as a discret measure. It's useful when you have several lines where "Factory Work Order" and "Parts Produced" have the same values as it is the case in your example.
Then I created a calculated field named Total with formula : Total(Sum[Parts Produced])). Then I set this field to be calculated with "Parts Produced".
