How to group categories below the desired percentage of a measure

[VayneDaryl]

Hello Everyone Good Day, I am new to Power Bi and Im working on a certain request on a project. I hope that somebody could help or somehow suggest some solutions or possible work around.

Given the visual below, I have to group all Departments with percentage below 4% as Others (all those in the red mark). I also have a Month and Year Filter so these values are dynamically changing depends on the filter. 

Thanks in advance guys.

Regards.

Hello Xiaoxin @v-shex-msft,

Thank you so much for your feedback, I really appreciate it. But the case is that calculated columns are not responsive to slicers. I have a month and year slicer so values are dynamically changing.

Hi @VayneDaryl,

AFAIK, current power bi desktop does not support to create dynamic calculate column or table based on filter effects.
If these percentage values are dynamic change based on filter effect, I'd like to suggest you create a new table with all category type values and "other".
After these steps, you can use this new table field as category of the pie chart and write a measure formula with variable and summarize function to summary raw table records based on category.
Then you can check if the current category is included in the list of category values that match condition and return correspond results, not matched records will be replaced to return blank and power bi will auto hide from the chart.(for 'other' group, it will summary 'less than 4% records’)

formula =
VAR summary =
    SUMMARIZE ( ALLSELECTED ( Table1 ), [Category], "Percent", 'percent formula' )
VAR topList =
    SELECTCOLUMNS ( FILTER ( summary, [Percent] > 0.04 ), "Category", [Category] )
VAR currCategory =
    SELECTEDVALUE ( newTable[Category] )
RETURN
    IF (
        currCategory IN topList,
        MAXX ( FILTER ( summary, [Category] = currCategory ), [Percent] ),
        IF (
            currCategory = "Other",
            SUMX ( FILTER ( summary, [Percent] < 0.04 ), [Percent] )
        )
    )

HI @VayneDaryl,

I'd like to suggest you add a calculated column to your table with if statement to check the current percentage and return the category value or "other" to regroup records, then you can use this to replace raw category fields to display new category on you chart.
