Converting calculated column into parameter

[mmvohra]

I have calculated column which is dependent on a measure. The measure itself is dependent on parameter. Now I want to convert the calculated column into measure form so that when the parameter updates "DaysInMarket" also gets updated. Suggest a solution please.

Calculated Column:
DaysInMarket =

VAR CurrentConsolidatedID = 'Work'[ConsolidatedID]

-- Earliest date for this ConsolidatedID

VAR First_Date =

    CALCULATE(

        MIN('Work'[Date]),

        'Work', 'Work'[ConsolidatedID] = CurrentConsolidatedID &&

        Repost Count ID check>0

)

-- Latest date for this ConsolidatedID

VAR Last_Date =

    CALCULATE(

        MAX('Work'[Date]),

       'Work', 'Work'[ConsolidatedID] = CurrentConsolidatedID &&

        Repost Count ID check >0

    )

RETURN

if ( 'Work'[Date]=Last_Date, DATEDIFF(First_Date, Last_Date, DAY),0)

Measure:

Repost Count ID check =

VAR Threshold = 'Parameter 2'[Parameter Value]

RETURN

CALCULATE(

    DISTINCTCOUNT('Work'[id]),

    FILTER(

       ALLEXCEPT('Work','Work'[ConsolidatedID]),

        VAR Previous_Date =

            CALCULATE(

                MIN('Work'[Date]),

                ALLEXCEPT('Work', 'Work'[ConsolidatedID])

            )

    VAR Initial_Mileage =

            CALCULATE(

                MIN('Work'[Mileage]),

                ALLEXCEPT('Work', 'Work'[ConsolidatedID]),

                'Work'[Date]= Previous_Date

            )

VAR BaselineID =

    CALCULATE(

        MIN('Work'[id]),

        ALLEXCEPT('Work','Work'[ConsolidatedID]),

        'Work'[Date] = Previous_Date

    )

VAR DIF= ABS('Work'[Mileage]-Initial_Mileage)

VAR Count_1=CALCULATE(COUNTROWS('Work'), ALLEXCEPT('Work','Work'[ConsolidatedID]))

RETURN

   DIF <= Threshold &&

    Count_1 > 1

    )  

)

Hi,

A calculated column won’t react to a parameter change because it’s only evaluated at refresh time. To make DaysInMarket update dynamically when Parameter 2 changes, you need to convert it into a measure and compute First/Last dates using a row-level condition (based on the parameter), then return the value only for the “last date” row (same behavior as your column).

Here’s a working pattern:

1) Create a row-level pass/fail measure (parameter-driven):

Pass Threshold :=
VAR Threshold = SELECTEDVALUE('Parameter 2'[Parameter Value], 0)

VAR PrevDate =
CALCULATE(
MIN('Work'[Date]),
ALLEXCEPT('Work', 'Work'[ConsolidatedID])
)

VAR InitialMileage =
CALCULATE(
MIN('Work'[Mileage]),
ALLEXCEPT('Work', 'Work'[ConsolidatedID]),
'Work'[Date] = PrevDate
)

VAR CountRowsCID =
CALCULATE(
COUNTROWS('Work'),
ALLEXCEPT('Work', 'Work'[ConsolidatedID])
)

VAR Dif = ABS( MAX('Work'[Mileage]) - InitialMileage )

RETURN
IF( CountRowsCID > 1 && Dif <= Threshold, 1, 0 )

2) Replace the calculated column with this measure:

DaysInMarket :=
VAR CurrentDate = SELECTEDVALUE('Work'[Date])

VAR ValidRows =
FILTER(
ALLEXCEPT('Work', 'Work'[ConsolidatedID]),
[Pass Threshold] = 1
)

VAR FirstDate = MINX(ValidRows, 'Work'[Date])
VAR LastDate = MAXX(ValidRows, 'Work'[Date])

RETURN
IF(
NOT ISBLANK(CurrentDate) && CurrentDate = LastDate,
DATEDIFF(FirstDate, LastDate, DAY),
0
)

This will now recalculate dynamically whenever the DaysInMarket parameter/threshold changes. It works best in a table/matrix where Work[Date] is in the visual (so the measure can identify the “last date” row).
