Add column with distinct count and conditions

[chela199]

Hello 

I'm facing some issues finding way to solve how to create a column that does the following:

A. Count distinct values according to a category, for example, count of different ids for pants, sweaters and t-shirts. 

B. Then take every distinct value per category and multiply by a fixed value like pants = 5, sweaters= 2, and t shirts=1 

C. Count distinct values of all categories.

D. Take point C and multiply by a fixed value according to a category like in B. 

E. Take the product of B/D and multiply by 100. 

Is this possible? I have accomplished to do so in several measures but I can not figure out how to create a column with the

Hi @chela199 ,

Please try this:

Column = 
VAR _category = 'Table'[Category]
VAR _A =
    CALCULATE (
        DISTINCTCOUNT ( 'Table'[ID] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Category] = _category )
    )
VAR _B =
    SUMX (
        VALUES ( 'Table'[Category] ),
        SWITCH ( _category, "pants", _A * 5, "sweaters", _A * 2, "t-shirts", _A )
    )
VAR _C =
    DISTINCTCOUNT ( 'Table'[ID] )
VAR _D =
    SUMX (
        VALUES ( 'Table'[Category] ),
        SWITCH ( _category, "pants", _C * 5, "sweaters", _C * 2, "t-shirts", _C )
    )
VAR _E =
    DIVIDE ( _B, _D ) * 100
RETURN
    _E

You can change the variable name after RETURN to check if the calculation at each step meets your needs. If this does not work, consider providing sample data and expected output.

Hi @chela199,

You can use EARLIER function to get the count based on different category. With that you would get a column that shows count of all IDs in pants category for all rows with pants and so on for all category. You can then multiply these values with your fixed value using IF conditions. Once you have B and D, division should be easy.

Mark this post as a solution if that works for you!
