Beast Mode Calculation

Mvolkmann

Okay, so still learning here. I am trying to calculate a waste percentage from used material to installed material.

Here's the data I'm working with… Hopefully this makes sense.

Column "Product Code Number"

Column "Quantity"

I want to use the following formula

((Product code number quantity(only for codes 10,11,12,13,14,15,16,20,21,30,40,50,60,61,70) - product code quantity(only for code 83)) / (Product code quantity(only for codes 10,11,12,13,14,15,16,20,21,30,40,50,60,61,70))

This is not working and I've been messing with it over and over and can't seem to get it right.

SUM(CASE WHEN Product Code Number = '10','11','12','13','14','15','16','20','21','30','40','50','60','61','70' THEN Quantity ELSE 0) - SUM(CASE WHEN Product Code Number = '83' AND Unit = 'SF' THEN Quantity ELSE 0)
/
SUM(CASE WHEN Product Code Number = '10','11','12','13','14','15','16','20','21','30','40','50','60','61','70' THEN Quantity ELSE 0)
END

Use IN instead of =

SUM(CASE WHEN Product Code Number IN ('10','11','12','13','14','15','16','20','21','30','40','50','60','61','70') THEN Quantity ELSE 0) - SUM(CASE WHEN Product Code Number = '83' AND Unit = 'SF' THEN Quantity ELSE 0)
/
SUM(CASE WHEN Product Code Number IN ('10','11','12','13','14','15','16','20','21','30','40','50','60','61','70') THEN Quantity ELSE 0)
END
