Get data from long fact table using foreign hierarchy

[Anonymous]

I have a long table that contains some dimensions and a value associated to them.

These dimensions have an incomplete hierarchy relation amognst them. In a simple chart I would like to display the value associated with the lowest selected hierarchy level. I include an example with only 1 dimension below (my real cas has 5).

Hierarchy table:

LEVEL 1	LEVEL2	LEVEL 3
Food	Fruits	Bananas
Food	Fruits	Apples
Food	Meat	Chicken
Food	Mushrooms	Mushrooms

DIMENSION	VALUE
Food	10000
Fruits	2000
Meat	3000
Bananas	500
Apples	500
Chicken	1500
Mushrooms	100

My expectation is to have a drilldown that at level 1 shows:

X	Y
Food	10000

At Level 2

X	Y
Fruits	2000
Meat	3000
Mushrooms	100

At Level 3 

X	Y
Bananas	500
Apples	500
Chicken	1500
Mushrooms	100

I believe this logic can be built using RELATED() but I haven't found a way to do so. What is the best way to create such logic in DAX? Is there an approach to embed that in the m power query load side?

Thanks in advance

Hi @Anonymous,

Please refer to below measure:

return value =
VAR isLevel1 =
    ISINSCOPE ( 'Hierarchy Table'[LEVEL 1] )
VAR isLevel2 =
    ISINSCOPE ( 'Hierarchy Table'[LEVEL2] )
VAR isLevel3 =
    ISINSCOPE ( 'Hierarchy Table'[LEVEL 3] )
RETURN
    IF (
        isLevel3 = TRUE (),
        CALCULATE (
            SUM ( 'Dimention Table'[VALUE] ),
            FILTER (
                ALLSELECTED ( 'Dimention Table' ),
                'Dimention Table'[DIMENSION] = SELECTEDVALUE ( 'Hierarchy Table'[LEVEL 3] )
            )
        ),
        IF (
            isLevel2 = TRUE (),
            CALCULATE (
                SUM ( 'Dimention Table'[VALUE] ),
                FILTER (
                    ALLSELECTED ( 'Dimention Table' ),
                    'Dimention Table'[DIMENSION] = SELECTEDVALUE ( 'Hierarchy Table'[LEVEL2] )
                )
            ),
            IF (
                isLevel1 = TRUE (),
                CALCULATE (
                    SUM ( 'Dimention Table'[VALUE] ),
                    FILTER (
                        ALLSELECTED ( 'Dimention Table' ),
                        'Dimention Table'[DIMENSION] = SELECTEDVALUE ( 'Hierarchy Table'[LEVEL 1] )
                    )
                )
            )
        )
    )

Hello @v-yulgu-msft,

Thanks a lot, your approach looks close to what I'm looking for.

Is there a more generic way to build this?

I will likely use more than 1 'Hierarchy Table' and perhaps I play around a bit with the number of levels.

Should I make 1 measure per 'Hierarchy Table' and 1 var per level in each hierarchy.

Yes. You should create one measure per 'Hierarchy Table' and define one variable per level in each hierarchy.
