Ranking by country and date

[Martynas_BI]

Hi,

I would like to rank the following 'Annual population' table by year and country.

For instance, there are 10 country categories each year. I would like the ranking to reset each year (please refer to the snip below)

Many thanks in advance.

One way to rank the 'Annual population' table by year and country, with the ranking resetting each year, is to use the RANKX function in DAX. Here's an example formula that implements this:

```
Rank = RANKX(
FILTER(
'Annual population',
'Annual population'[Country] = EARLIER('Annual population'[Country]) &&
'Annual population'[Year] = EARLIER('Annual population'[Year])
),
'Annual population'[Population],
,
DESC,
Dense
)
```

Hope this helps!

Hi @aaitelkadi ,

Unfortunately, I get an error using this DAX formula regarding the EARLIER function

Any advice?

I used the following code and it worked:

Ranking =

VAR CurrentYear = YEAR('Annual population'[Date])

RETURN

    RANKX(

        FILTER(

            ALL('Annual population'),

            YEAR('Annual population'[Date]) = CurrentYear

        ),

        'Annual population'[Population],

        ,

        DESC,

        Dense

    )

Perfect. I am glad it worked for you.
