Dynamic Date RANKX() by Date Selected on Slicer

wifc5013 — Tue, 15 Feb 2022 15:51:14 GMT

I am looking for a a DAX calculated column or measure that will rank dates dynamically based on a slicer date selection.

The end goal is to calculate 2 tables, one with the 'latest date selected' (index = 1) and one with the 'previous date' (index = 2), based on the slicer selection. Typically I would use DATEADD() or PREVIOUSDAY() for this, but the dates are not contiguous, therefore it seemed an index was needed, but I could be wrong.

The measure/column needs to dynamically adjust to the filter selection. Thank you kindly for your consideration

wifc5013 , Try a new measure like

Countx(allselected(Table), Table[Date]>= min(Table[DAte]), Table[DAte])

Thanks for your efforts. I create a measure as follows, but the lasta parameter in the measure gives error:

Countx(allselected(Table), Table[Date]>= min(Table[DAte]), Table[DAte])

"Too many arguments passed to Countx function"

If i remove that, so measure become:

I receive error:

Calculation error in measure 'USER_CASHPROMPT_PNL_RESULTS'[__RANKY]: The function COUNTX cannot work with values of type Boolean.

__RANKY = Countx(allselected(Table),Table[EOD_DATE] >= max(Table[EOD_DATE]))

Hi wifc5013 ,

Please firstly create a calendar table

Calendar = CALENDAR(MIN('Table'[EOD_DATE]),MAX('Table'[EOD_DATE]))

Then create rank measure:

Rank = var _rank=RANKX(FILTER(ALL('Table'),[EOD_DATE]<=MAX('Calendar'[Date])),CALCULATE(MAX('Table'[EOD_DATE])),,DESC) return IF(MAX('Table'[EOD_DATE]) >MAX('Calendar'[Date]),BLANK(), _rank)
