## Weighted Result based on Recent Month

 Name Month Rating(1-5) Current  Month = 60% weighted Safety January 1 -1 Month = 30% Weighted Safety February 1 -2 Month = 10% Weighted Safety March 5 Safety April 5 March's  Safety Rating = 3.4 Collaboration January 5 April's Safety Rating = 4.6 Collaboration February 1 Collaboration March 5 March's Collaboration Rating = 3.8 Collaboration April 4 April's Collaboration Rating = 4

In Dax, anyone can tell me how to get the result of the march's safety and collaboration rating when March is select,  and when April is selected, April result get output or what would be the best solution?

## Re: Weighted Result based on Recent Month

Step 1 - convert your "month" column to a date (first of the month); create a relationship to a date table

Step 2 - 3 measures

```PM Rating = CALCULATE(SUM(Weighted[Rating]), PREVIOUSMONTH(Weighted[Dt]))

PPM Rating = CALCULATE(SUM(Weighted[Rating]), PREVIOUSMONTH(PREVIOUSMONTH(Weighted[Dt])))

This Month Rating = SUM(Weighted[Rating])*.6 + [PM Rating]*.3 + [PPM Rating]*.1```

You may want to do some "IF (ISBLANK ( " logic in the measures so that you don't get values for months that don't have 2 previous months.

Hope this helps,
