The script 

sum =

SUMX(

    FILTER(

         Table1;

         Table1[product] = EARLIER(Table1[product])

    );

    Table1[sales]

)

The Error :

EARLIER(Table1[product]) # Parameter is not correct type cannot find name 'product'

What's wrong with the script above ? * not able to test this script: 

rank = RANKX( ALL(Table1); Table1[sum]; ;; "Dense" )

before fixed the sum approach

Solution

  • The script is designed for a calculated column, not a measure. If you enter it as a measure, EARLIER has no "previous" row context to refer to, and gives you the error.

    Create a measure:

    Total Sales = SUM(Table1[sales])

    This measure will be used to show sales.

    Create another measure:

    Sales by Product =
SUMX(
  VALUES(Table1[product]);
  CALCULATE([Total Sales]; ALL(Table1[date]))
)

    This measure will show sales by product ignoring dates.

    Third measure:

    Sale Rank = 
  RANKX(
     ALL(Table1[product]; Table1[date]); 
     [Sales by Product];;DESC;Dense)

    Create a report with product and dates on a pivot, and drop all 3 measures into it. Result:

    Tweak RANKX parameters to change the ranking mode, if necessary.
