Filter Dax Function

[hullyf]

Hi,

I need help with a dax function.

Background - we have 3 different product sizes - Full Size, Mini, & Value Size.

I'm trying to create a chart that has Full Size & Value Size combined as one, and all 3 combined as one to show growth of products w/ Mini vs. growth of products w/out.

I was able to get the Dax correct for sales, but I'm trying to pull growth instead. 

The below Dax worked for me to pull sales excluding Minis, but I'm trying to pull GROWTH excl. minis (it's a measure labeled Sales@USD_%MTD_LY)

Excl. Minis = SUMx(FILTER('Sales by SKU', RELATED(SKU[Product Size]) <> "Mini"), 'Sales by SKU'[Sales@USD])
