Problem with CALCULATE / FILTER

Hi

I'm trying to produce a table from some simple Sales data in the following format:

 

 

I'd like to produce a table showing Customer, Number of Sales and "Number of Sales to Major Customers", where "Major Customer" is one who's made more than 50 purchases.  

Currently, only one company (MegaMart)has made more than 50 purchases:

. but I don't want to hard-doe a filter on Mega MArt, as, in the real world, other companies would beceome "Major Customers" with a few more sales.

 

So:  I created some measures, including one using a filter on count of sales :

 

Number of Sales = COUNTROWS(Sales)

Sales to Major Customers = CALCULATE([Number of Sales],FILTER(Sales,[Number of Sales]>50))

.. with another "Quick & Dirty" measure to check the numbers are correct

CheckCount = CALCULATE([Number of Sales],Sales[Customer]="MegaMart Inc")

 

But I haven't got the result I want:

 

This suggests that my "Sales to Major Customers" measure is incorrect, but I can't see why. Coudl anyone help?

Thanks!

    see if this is what you had in mind:

    Sales to Major Customers = 
SUMX (
       CALCULATETABLE(
           Sales,
            FILTER(
                ADDCOLUMNS(
                    SUMMARIZE(
                        Sales,
                        Customers[Customer]
                    ),
               "Sales by Customer", 
                CALCULATE( 
                    COUNTROWS( Sales), 
                        FILTER( 
                            ALL ( Sales), 
                            Sales[Customer] = EARLIER(Customers[Customer]))
                )
                ),
           [Sales by Customer] > 50
            )
       ),
       [NumberofSales]       
)

    It can look overly complex, but if you take it bit-by-bit it's really not that  bad. Just remember to work from the inside out. summarize and addcolumns are just a way to make a virtual table, and then I added a column to that table and used that to filter sales since filters are tables. But if this is for an intro type course, you would be better served trying for a simplie example.

    Try:

    Total Purchases >50 = 
CALCULATE(
    [Number of Sales],
    FILTER(
        Customers,
        [Number of Sales] >50
    )
)

      Nick

       

      Thanksfor the suggestion but it doesn't work. BUT I think I have a clue to the problem:

       

      If I change my Measure to 

      Sales to Major Customers = CALCULATE([NumberofSales], FILTER(Customers,[NumberofSales]>20))

      I get: 

       

      I think the significance of the 27 is that there are > 20 Carrot sales for MegaMart, but no other sales > 10 for any other customer/product combo:

       

      If I change my Measure to 

      Sales to Major Customers = CALCULATE([NumberofSales], FILTER(Customers,[NumberofSales]>10))

      I get: 

       

      So, what I think I need to do is to change my measuree so it counts ALL sales for each customer, ignoring the "Product" context. I'm not sure how to do this - maybe use ALL? But how?

       

      Any suggestions?

       

      Thanks!
