SelectedValue as Slicer for MultiLanguage Reports

[ceren1997]

Hi,

I'm working on creating a multi language report. Since our initial report has a lot pages, i am trying to build a report where i use a language slicer and dynamically change the values.

However I dont know how to achieve it on slicers. I've tried to create a calculated column:

TranslatedMonth =

VAR SelectedLanguage = SELECTEDVALUE('Language'[LanguageId])

RETURN

SWITCH(

    SelectedLanguage,

    1, 'Date'[MonthName],

    2, 'Date'[MonthName_EN]

)
And I used it as my date slicer. However it just gives 24 (12 months for 2 languages) blank values.

Is there a way to achieve this or do i need bridge tables etc? I dont want to change the table structure much, im looking for more of a dynamic solution using measures.

Many thanks in advance!

Thanks @danextian your approach was very beneficial!

I've also figured out an additional solution.

I've use a field parameter for my date slicer where i have both MonthName and MonthName_EN columns. 

I've noticed MonthName takes the id 0 and monthname_EN takes the id 1 and there is no way to alter that.

So, i've updated my language table in accordance and managed the relationship between the date field parameter and language table.

Now, it works as desired.

Hi @ceren1997 - you can create bridge table if you dont have it as like below. 

Language =
DATATABLE(
"LanguageId", INTEGER,
"LanguageName", STRING,
{
{1, "English"},
{2, "OtherLanguage"}
}
)

after that instead of calculated column, create a measure as like below to work dynamically switch the MonthName based on the selected language. This measure can then be used in your slicers or visuals

attached pbix file FYR.

Hope this helps.

Thank you so much, this would also work perfectly!

Hi @ceren1997 

Calculated columns don't respond to slicer selections. Within the calculated column context, it encounters a blank value since SELECTEDVALUE returns blank by default. It remains unaware if any selection has been made in the slicer.

Try using field parameters to switch between columns using a slicer.

Hi @danextian,

Thank you so much for this brilliant idea! 

I've never worked with parameters before so im a little confused. Here is my language table:

And my date table simply has MonthName, MonthName_EN columns in addition to necessary date columns.

Ive created 2 parameters, one for the languageid and the other is for monthnames, ive added both columns to the parameter. 
However i couldnt manage to create relationship between those parameters.

Could you please tell me where i am going wrong?

Hi @ceren1997 

I was referring to this:

https://learn.microsoft.com/en-us/power-bi/create-reports/power-bi-field-parameters

Just make sure that single select is enabled for the slicer to avoid showing multiple columns at a time.

It still is in preview so you may need to enable it first.
