Dynamic Ranking of Product in Hierarchy

JayJay11 — Fri, 07 Jan 2022 12:17:41 GMT

Hello all,

this is the first I am completely stuck with a problem in DAX. My problem is supposedly simple, but I believe the RANKX function is very hard to apply in real-world problems.

Desired end-result

I simply want to rank 3 products in a geographical hierarchy, considering also the slicer context of the report page (geography and a date range).

Both rows and columns are based on fields. Ideally, the table has just one measure.

The ranking shall be based on the latest date selected on the sheet.

This is the fact table

This is the geography table

The date table is just a standard calender connected via the date field.

I understand from reading countless other posts on RANKX issues, that in the end I could generate mutiple variables in a measure and then check with ISFILTERED() the current hierarchy level. I guess the issue that I have, is how to calculate the ranking on an aggregated level, like here Subregion?

Can someone provide a solution pattern for this?

Many thanks in advance!

No one? Is this actually unsolvable with DAX?

Hi, JayJay11

You can try the following methods.

New column:

Rank = RANKX ( FILTER ( 'Fact', [Country_ISO] = EARLIER ( 'Fact'[Country_ISO] ) && [Date] = EARLIER ( 'Fact'[Date] ) ), [Value], , DESC )

Is this the output you expect?

Dear Charlotte,

many thanks for this suggestion. I understand, this solution uses a calculated column. We however need the ranking to be dynamic and change with the filter context. As such, a measure would be needed.

Do you have a solution for a measure?

Thank you!

Hi, JayJay11

Measure:

Rank Measure = RANKX ( FILTER ( ALL ( 'Fact' ), [Country_ISO] = MAX ( 'Fact'[Country_ISO] ) && [Date] = MAX ( 'Fact'[Date] ) ), CALCULATE ( SUM ( 'Fact'[Value] ) ), , )
