Rankx gives all 1

[bhumikasardana]

Hi,

I need to add measure called RankSeries to rank each series by its viewing figures to get following output

Upon using this DAX formula ,
RankSeries = RANKX(ALL(Series),CALCULATE(SUM(Series[Viewers (m)])),,ASC)

Goal is achieved but when I replace Table-> All(series) with Column All(Series[Series]) , i.e

RankSeries = RANKX(ALL(Series[Series]),CALCULATE(SUM(Series[Viewers (m)])),,ASC)

value for the same comes out as 

I don't understand why ?

Hi  @bhumikasardana ,

ALL used as a filter argument is filter modifier. It removes the filter on its argument.

When the argument is a table, it removes the filter over the entire expanded table (the table specified as argument). Whent the argument is one or more columns, it removes the filters over the specified columns.

Filter removals happen during the fourth step in the CALCULATE execution, after the context transition and before the expression evaluation

The explanation of the CALCULATE execution step can be found in the DAX Guide

In the Measure 1, all filters are removed from the Series table. In the Measure 2, only the filter existing over Series[Series] is removed

@bhumikasardana , if you add any other column than the column in Rank, that rank will be inside that column/s that is why the second rank behaves like that

you need add all columns in visual

RankSeries = RANKX(ALL(Series[Series], Series[channel], Series[episode] ,Series[timeslot]) ,CALCULATE(SUM(Series[Viewers (m)])),,ASC)

For Rank Refer these links

Okay, so basically when I select All(tablename) inside rankx, irrespective of other column my values won't be alter.But, if I select a All(columnname) then upon adding more columns in visual my rank would be affected?How do I know what to use when?i.e it should be All(Tablename) or All(Columname)?
