Dynamic Top N Categories and Top N Sub Categories and Top N Brand

[DeepDive]

Hi All, Am using below Curbal's concept for Top N Categories, but under Categories I have Sub-Categories and under Sub-Categories, I have Brands also. At individual level, all is working fine but when I drill down or expand categories it shows me correct for Sub-categories but for Categories it gives me all categories.

Hi, @DeepDive 

Based on your description, I created data to reproduce your scenario. The pbix file is attached in the end.

Table:

You may create a hat-if parameter as below.

Here are the calculated columns and measures:

Calculated column:
Level2 = [Category]&"-"&[Sub Category]
Level3 = [Category]&"-"&[Sub Category]&"-"&[Brand]

Measure:
Visual Control = 
var _categorytopn = 
SELECTCOLUMNS(
    TOPN(
        SELECTEDVALUE(Parameter[Parameter]),
        SUMMARIZE(
        ALL('Table'),
        'Table'[Category],
        "Sales",SUM('Table'[Sales])
        ),
        [Sales]
    ),
    "Category",
    [Category]
)
var _subcategorytopn = 
SELECTCOLUMNS(
    TOPN(
        SELECTEDVALUE(Parameter[Parameter]), 
        SUMMARIZE(
            FILTER(
               ALL('Table'),
               'Table'[Category]=SELECTEDVALUE('Table'[Category])
            ),
            'Table'[Category],
            'Table'[Sub Category],
            "Sales",SUM('Table'[Sales])
        ),
        [Sales]
    ),
    "Level2",
    [Category]&"-"&[Sub Category]
)
var _brandtopn = 
SELECTCOLUMNS(
    TOPN(
        SELECTEDVALUE(Parameter[Parameter]),
            SUMMARIZE(
                FILTER(
                    ALL('Table'),
                    'Table'[Category]=SELECTEDVALUE('Table'[Category])&&
                    'Table'[Sub Category]=SELECTEDVALUE('Table'[Sub Category])
                ),
                'Table'[Category],
                'Table'[Sub Category],
                'Table'[Brand],
                "Sales",SUM('Table'[Sales])
            ),     
        [Sales]
    ),
    "Level3",
    [Category]&"-"&[Sub Category]&"-"&[Brand]
)

return
IF(
    ISINSCOPE('Table'[Category])&&NOT(ISINSCOPE('Table'[Sub Category]))&&NOT(ISINSCOPE('Table'[Brand])),
    IF(
        SELECTEDVALUE('Table'[Category]) in _categorytopn,
        1,0
    ),
    IF(
        ISINSCOPE('Table'[Sub Category])&&NOT(ISINSCOPE('Table'[Brand])),
        IF(      
            SELECTEDVALUE('Table'[Category]) in _categorytopn&&
            SELECTEDVALUE('Table'[Level2]) in _subcategorytopn,
            1,0
        ),
        IF(
            ISINSCOPE('Table'[Brand]),
            IF(
                SELECTEDVALUE('Table'[Category]) in _categorytopn&&
                SELECTEDVALUE('Table'[Level2]) in _subcategorytopn&&
                SELECTEDVALUE('Table'[Level3]) in _brandtopn,
                1,0
            )
        )
    )
)

Finally you may put the measure in the visual level filter and use the parameter to filter the topn result. Because the maximum count for 'Brand' is 2, there are only two brand in 'Brand' level even though the slicer is set as 3. It depends on your data.

Hi Amit, thanks for your reply.

My requirement is to show YTD at all levels only for selected top N using one slicer only....
