Measures by classification

[Anonymous]

Hi Experts,

I have a question that struggle me for a time, would anyone can help me to solve?
I would like to create 4 measures (It's 2 types of measure in fact)

Please find the raw sample file for download

There is a CODE contains A, B and the others, in this case we will only focus on A & B. 

Customers will be classified into 
A only - Yellow
B only - Orange

Mixed: A - Green

Mixed: B - Blue

The expected result is to create 4 Measures to get the sum of A only, B only, Mixed: A, Mixed: B

Note the results will vary with the time of selection, so it is no way to create Column to solve.

Expected result:

The question looks simple, but it struggle me for a time really.

Many many thanks
