Validate Slicer Selection

Hello

 

I have a period column in a table that I am using as a slicer. It is of type date and I am using it as a Date Hierarchy. 

I need to validate if the user selected the same number of months in the years, for example: if in 2020, January and February are selected and in 2021, January, February and March are selected, i need it to display "months missing from selection". If there is a match in the number of months selected in multiple years, i need it to display "months selected correctly".

I have no idea how to start this.

Any suggestion is appreciated.

 

Thank you

    Anonymous here you go, add following measure

    Month Selected = 
VAR __year = 
SUMMARIZE ( 
    'Calendar', [Year], "@Months", CONCATENATEX ( VALUES ( 'Calendar'[Month] ), [Month], "," ) 
)
VAR __status =
IF ( COUNTROWS ( VALUES ( 'Calendar'[Year] ) ) = 1, -1,
    COUNTX ( 
        SUMMARIZE ( __year, [@Months], "@Rowcount", COUNTROWS ( __year ) ), [@Rowcount] 
    ) 
)
RETURN
SWITCH ( 
    __status,
    1, "Valid Selection", 
    -1, "Invalid Selecton - Only months selected in one year",
    "Invalid Selection - not same months selected"
)

    count months : =
    COUNTROWS(VALUES('Calendar'[Month Name]))

     

    count years : =
    COUNTROWS(VALUES('Calendar'[Year]))
     
    Selection Validate Measure =
    VAR monthscount =
    COUNTROWS ( VALUES ( 'Calendar'[Month Name] ) )
    VAR yearscount =
    COUNTROWS ( VALUES ( 'Calendar'[Year] ) )
    VAR newtablemonth =
    ADDCOLUMNS ( ALLSELECTED ( 'Calendar'[Month] ), "@countyears", [count years :] )
    VAR newtableyear =
    ADDCOLUMNS (
    ALLSELECTED ( 'Calendar'[Year] ),
    "@countmonths", [count months :]
    )
    RETURN
    IF (
    monthscount = MINX ( newtableyear, [@countmonths] )
    && yearscount = MINX ( newtablemonth, [@countyears] ),
    "Months selected correctly",
    "Months missing from selection"
    )

      thank you for your reply. your solution only works if i select something in both years. if i only select in one of the years, it is no longer working and this is a scenario that would happen often. i appreciate your suggestion

    Anonymous one question. what happens if the user selects Jan/Feb in 2019 and Nov/Dec in 2020, still the user selected two months in both of the years but these are different months? Is this the right selection or month selection have to be the same for each year or just the count of month matter, not the actual months?
