How to group by summed amounts?

[Mendel]

I'm trying to figure out how take the total sales amount for filtered list of customers, catagorize them (e.g., Large, Medium, Small) and provide a count for those catagories.

For instance, if I want Large >= $100K, Med $25K to $100K , Small under $25K and my table is:

Customer      Product     Amount

================================

Customer A     ABC       $80,000

Customer A     XYZ       $40,000

Customer B     ABC       $20,000

Customer B     XYZ       $60,000

Customer c     XYZ        $7,000

I would like to be able to produce:

Category      Count

==============

Large             1

Medium        1

Small             1

If I were using Tableau, I would use a CASE statement and a LEVEL OF DETAIL calc, but I can't figure out how to do this with DAX. Also, I'm using Direct Query, so functions like ALLCOLUMNS won't work.

Actually upon further examination, the solution isn't using the additional tables, but it still doesn't work properly when any filter is applied.

This solution breaks the data query out into separate joined datasets. My data is structured like shown above, in a single flat file. As such, this solutions doesn't work as it counts multiple rows for each customer and doesn't aggregate them. I need to keep my original query as to much stuff is already built on it, but I guess I could build new queries to use this solution. I just wish I could do it as is, with different DAX statement.

Hi,

Please check the below picture and the attached pbix file.

It is for creating measures to solve.

Customers count by category: =
CALCULATE (
    COUNTROWS ( Customer ),
    FILTER (
        Customer,
        COUNTROWS (
            FILTER (
                Category,
                [Sales amount:] >= Category[Min]
                    && [Sales amount:] < Category[Max]
            )
        ) >= 1
    )
)
