4 weeks average based on weekrank
Hi,
I would like to calculate the 4 weeks average based on weekrank.
example:
Weekno rank value
20 1 10
19 2 15
18 3 10
17 4 9
20 5 5
Weekno and rank comes from the datetable and value is calculated measure.
My desired outcome for weekno 20 4weeks average= 10+15+10+9 = 11 etc....
I tried the following the measure but it does not show me the average:
4 weeks average = var _ranktable = calculatedtable(values(rank);filter(allselected(rank);rank<=max(rank)+3 && rank>=max(rank)))
return
averagex =(_ranktable, value)
Any suggestions?
Hi Anonymous
I build two table to have a test.
Date Table:
Weeknom and Rank columns are calculated columns.
Weeknom = WEEKNUM('Date'[Date],2)Rank = RANKX('Date','Date'[Date],,DESC,Dense)Result:
Value Table:
Build Value measure in Date table:
Value = CALCULATE(SUM('Value'[Value]),FILTER('Value','Value'[Date]=MAX('Date'[Date])))Then I build a measure to achieve your goal.
4 weeks average = VAR _Totalvalue= SUMX ( FILTER ( ALL ( 'Date' ), 'Date'[Rank] <= MAX ( 'Date'[Rank] ) + 3 && 'Date'[Rank] >= MAX ( 'Date'[Rank] ) ), [Value] ) return IF ( MAXX ( ALL ( 'Date' ), 'Date'[Rank] ) - SUM ( 'Date'[Rank] ) >= 3, DIVIDE(_Totalvalue,4), BLANK() )Result:

https://medium.com/@amitchandak.1978/power-bi-wtd-questions-time-intelligence-4-5-98c30fab69d3Anonymous , Try like
Last 4 Week = CALCULATE(Average(Table[value]),FILTER(all('Table'),'Table'[Rank]>=min('Table'[Rank])-4
&& 'Table'[Rank]<=max('Table'[Rank])))
Last 4 Week = CALCULATE(Average(Table[value]),FILTER(allselected('Table'),'Table'[Rank]>=min('Table'[Rank])-4
&& 'Table'[Rank]<=max('Table'[Rank])))But prefer to have a week table and week and rank there
Like
Last 4 Week = CALCULATE(Average(Table[value]),FILTER(all('WEEK'),'WEEK'[Rank]>=min('WEEK'[Rank])-4
&& 'WEEK'[Rank]<=max('WEEK'[Rank])))
Last 4 Week = CALCULATE(Average(Table[value]),FILTER(allselected('WEEK'),'WEEK'[Rank]>=min('WEEK'[Rank])-4
&& 'WEEK'[Rank]<=max('WEEK'[Rank])))

Hi Anonymous this is extremly helpful - but I would like to do it for the last 4 weeks excluding the latest week - so here in this example, I want to average rank 2 to 5 instead of 1 to 4. How can I adjust your formula to do that? Thanks so much!
