12 week average
I have a visual that displays a table with a "Week Ending Tuesday" column as a date and a DAX measure for "Total Accounts Receivable". I need to create a new DAX measure that calculates the 12-week average of the "Total Accounts Receivable" measure. Consider the date filter of financial year that starts in July. Thanks in advance 🙂

Have these new columns in Date Table, Week Rank is Important in Date/Week Table
Week Rank = RANKX('Date','Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX('Date','Date'[Year Week],,ASC,Dense) //YYYYWW formatLast 12 weeks = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-12 && 'Date'[Week Rank]<=max('Date'[Week Rank])))
For tuesday week

Need of an Independent Date Table:https://www.youtube.com/watch?v=44fGGmg9fHI
//Date1 is independent Date table, Date is joined with Table
new measure =
var _max = maxx(allselected(Date1),Date1[Week Rank])
var _min = _max -1
return
calculate( sum(Table[Value]), filter('Date', 'Date'[Week Rank] >=_min && 'Date'[Week Rank] <=_max))
