Reverse sort in date table

[francofava]

I have created a date table using the code below. 

Accounting_Posting_Date = 

ADDCOLUMNS (

CALENDAR (DATE(2015,1,1), DATE(2030,12,31)),

"DateAsInteger", FORMAT ( [Date], "YYYYMMDD" ),

"Period", FORMAT ( [Date], "YYYYMM" ),

"Year", YEAR ( [Date] ),

"Monthnumber", FORMAT ( [Date], "MM" ),

"YearMonthnumber", FORMAT ( [Date], "YYYY/MM" ),

"YearMonthShort", FORMAT ( [Date], "YYYY/mmm" ),

"MonthNameShort", FORMAT ( [Date], "mmm" ),

"MonthNameLong", FORMAT ( [Date], "mmmm" ),

"DayOfWeekNumber", WEEKDAY ( [Date] ),

"DayOfWeek", FORMAT ( [Date], "dddd" ),

"DayOfWeekShort", FORMAT ( [Date], "ddd" ),

"Quarter", "Q" & FORMAT ( [Date], "Q" ),

"YearQuarter", FORMAT ( [Date], "YYYY" ) & "/Q" & FORMAT ( [Date], "Q" )

)

I am using the PERIOD in a matrix column, but cannot manage to reverse the periods.

I've tried creating a new column

 "RANK_" = -Accounting_Posting_date[Period] 

and then use it to sort the period column but I get an error message about a circular dependency.

thanks!

I've managed to solve it by adding the column directly when creating the table and then referring to it when sorting the other columns

Accounting_Posting_Date =

ADDCOLUMNS (

CALENDAR (DATE(2015,1,1), DATE(2030,12,31)),

"DateAsInteger", FORMAT ( [Date], "YYYYMMDD" ),

"Period", FORMAT ( [Date], "YYYYMM" ),

"Year", YEAR ( [Date] ),

"Monthnumber", FORMAT ( [Date], "MM" ),

"YearMonthnumber", FORMAT ( [Date], "YYYY/MM" ),

"YearMonthShort", FORMAT ( [Date], "YYYY/mmm" ),

"MonthNameShort", FORMAT ( [Date], "mmm" ),

"MonthNameLong", FORMAT ( [Date], "mmmm" ),

"DayOfWeekNumber", WEEKDAY ( [Date] ),

"DayOfWeek", FORMAT ( [Date], "dddd" ),

"DayOfWeekShort", FORMAT ( [Date], "ddd" ),

"Quarter", "Q" & FORMAT ( [Date], "Q" ),

"YearQuarter", FORMAT ( [Date], "YYYY" ) & "/Q" & FORMAT ( [Date], "Q" ),

"Period_rank", -value(FORMAT ( [Date], "YYYYMM" ))

)

@francofava 

you should create an index and then sort you "Period" column by the index. 

Try to sort it by "Month Number" and see what happens.

thanks @Uspace87 

Can I do this in DAX?

the few examples that I've tried also gave me the circular dependency error

@francofava 

you don't need to do it in dax.

In you calendar table just sort you "Period" column by "Month_Year". The first time it will do it descending and the ascending or the other way around.
