Measure or calculation with user input (slicer or filter)

[moia79]

dear PBI gurus

am struggling to find the easier way to create a calculation / measure with a dynamic input from user.

my starting table is as follows

item	item description	FY	Month	dimension	Quantity
ABC	ABC-Description	2021	1	Ordered	55
ABC	ABC-Description	2021	1	forecast current month	60
ABC	ABC-Description	2021	1	forecast m-1	70
ABC	ABC-Description	2021	1	forecast m-2	70
ABC	ABC-Description	2021	1	forecast m-3	100

I need, for each item, to calculate a formula with "ordered" as fix input and variable selection of "corecast m-*". The complete formula is = ABS(Ordered - Forecast M-*)/(ABS(Ordered)+ABS(Forecast M-*)) and I would like to give possibility for each user to switch from "forecast m-1" to "forecast m-3" using a slicer or a filter.

Ending result would be a table like

ITEM    Item Descriptoion     Ordered      Fcast M-* (sselected by user)     Formula result

thanks @v-yanjiang-msft 

it works greatly. The only issue I've seen is that - since by table has multiple entry / groups - it has a strange behavior when I activate the total at the bottom of each column - meaning to calculate the same on aggregate level (imagine I need to aggregate the item per product family or per customer.

Is there anything I can do to allow also the total to display the sum of all the rows in a column correctly?

thanks

Hi @moia79 ,

Sorry I'm not very clear what you mean. When I turn on the total, it gets the result.

If your real sample is more complicated, would you like to expain more or give an example?

sorry, I was too quick in answering 🙂

so, an example of my dataset is as follows

the single rows are calculated correctly, however the total instead of being the sum of all entries shows only the max value (it seems), I would rather see the sum of all "Ordered" and "Forecast". Is it possible by adding a "SUM" operation in the formula?

thanks for your king feedback

Hi @moia79 ,

Sorry for the late reply, I modify my sample to contain more items.

Then modify the formula like this:

Ordered =
VAR _T =
    SUMMARIZE (
        'Table',
        'Table'[Item],
        "Ordered",
            MAXX (
                FILTER (
                    ALL ( 'Table' ),
                    'Table'[Item] = MAX ( 'Table'[Item] )
                        && 'Table'[dimension] = "Ordered"
                ),
                'Table'[Quantity]
            )
    )
RETURN
    SUMX ( _T, [Ordered] )

Fcast M-* =
VAR _T =
    SUMMARIZE (
        'Table',
        'Table'[Item],
        "Fcast M-",
            MAXX (
                FILTER ( 'Table', 'Table'[dimension] = SELECTEDVALUE ( 'Table'[dimension] ) ),
                'Table'[Quantity]
            )
    )
RETURN
    SUMX ( _T, [Fcast M-] )

Formula result =
VAR _T =
    SUMMARIZE (
        'Table',
        'Table'[Item],
        "Formula resut",
            ABS ( [Ordered] - [Fcast M-*] )
                / ( ABS ( [Ordered] ) + ABS ( [Fcast M-*] ) )
    )
RETURN
    SUMX ( _T, [Formula resut] )

Get the correct result:

it does work 🙂

Hi @moia79 ,

According to your description, here's my solution.

You can only use measures, because the value of calculated columns can't be affected by slicer. Create three measures.

Ordered =
MAXX (
    FILTER (
        ALL ( 'Table' ),
        'Table'[Item] = MAX ( 'Table'[Item] )
            && 'Table'[dimension] = "Ordered"
    ),
    'Table'[Quantity]
)

Fcast M-* =
MAXX (
    FILTER ( 'Table', 'Table'[dimension] = SELECTEDVALUE ( 'Table'[dimension] ) ),
    'Table'[Quantity]
)

Formula result =
ABS ( [Ordered] - [Fcast M-*] )
    / ( ABS ( [Ordered] ) + ABS ( [Fcast M-*] ) )

Get the result.
