Comments: Tableau does not allow a summation of a summation, so it isn't possible to streamline this calculation with intermediate variables. The logic for testing whether there is a stock-out is included in 'Stockouts - <vaccine name>' calculations as well as in the 'Stockouts - Vaccine' calculation.
