Hello,

I have an excel file which contains the different products ordored by a company every month. See the table below :

Example :

Rena.

And add one more filter in this expression via ALL('Data-Products').

 

ColorChanges = 
var _c = CALCULATE(MAX('Data-Products'[Color]),PREVIOUSMONTH('Data-Products'[Month]),ALL('Data-Products'))
return
IF(not(ISBLANK(_c)) && _c<>MAX('Data-Products'[Color]),MAX('Data-Products'[Color]))

Hi @Anonymous ,

 

You can do that by creating two measure, one named new color and another new stock.

New Color =
VAR _c =
    CALCULATE ( MAX ( 'Table'[Color] ), PREVIOUSMONTH ( 'Table'[Month] ) )
RETURN
    IF (
        NOT ( ISBLANK ( _c ) )
            && _c <> MAX ( 'Table'[Color] ),
        MAX ( 'Table'[Color] )
    )


New Stock =
VAR _s =
    CALCULATE ( MAX ( 'Table'[Stock] ), PREVIOUSMONTH ( 'Table'[Month] ) )
RETURN
    IF (
        NOT ( ISBLANK ( _s ) )
            && _s <> MAX ( 'Table'[Stock] ),
        MAX ( 'Table'[Stock] )
    )

Result:

If you want get the result dynamicly by slicer. Try this:

Measure =
VAR _select =
    SELECTEDVALUE ( 'Slicer'[Compare] )
VAR _color =
    CALCULATE ( MAX ( 'Table'[Color] ), PREVIOUSMONTH ( 'Table'[Month] ) )
VAR _stock =
    CALCULATE ( MAX ( 'Table'[Stock] ), PREVIOUSMONTH ( 'Table'[Month] ) )
VAR _switch_result =
    SWITCH ( _select, "Color", MAX ( 'Table'[Color] ), MAX ( 'Table'[Stock] ) )
VAR _map_column =
    SWITCH (
        _select,
        "Color",
            _color <> MAX ( 'Table'[Color] )
                && NOT ( ISBLANK ( _color ) ),
        _stock <> MAX ( 'Table'[Stock] )
            && NOT ( ISBLANK ( _stock ) )
    )
RETURN
    IF ( _map_column, _switch_result )

Result:

Hello,

Thanks for the response but it does not work for me. I have this error : 

 

Rena_0-1652718635864.png

It says that column specified in the "PREVIOUSMONTH" function is not date type i don't understand why

Hi @Anonymous ,

 

The type of this [Month] should be date. For example, 2022-05, you can change it to 2022-05-01, and format it as "yyyy-mm".
