Trying to calculate Moving Range

[Anonymous]

Getting this error.

Moving Range =

VAR EarlierTime =

    CALCULATE (

        MAX ( SPC[Date] ),

        FILTER (

            ALLSELECTED(SPC[Date]),

            SPC[Date] < SELECTEDVALUE ( SPC[Date])

        )

    )

VAR EarlierMeasureValue =

    CALCULATE ( SUM ( SPC[LastDone] ), SPC[Date] = EarlierTime)

RETURN

ABS ( EarlierMeasureValue - SUM ( SPC[LastDone] ))

LastDone is calculated as:

LastDone =

VAR _latest =

    GROUPBY (

        'GIS Request Monitor',

        'GIS Request Monitor'[Date],

        "@latest", MAXX ( CURRENTGROUP (), 'GIS Request Monitor'[Date_Time] )

    )

RETURN

    CALCULATE (

        SUM ( 'GIS Request Monitor'[Done_per_Day] ),

        TREATAS ( _latest, 'GIS Request Monitor'[Date], 'GIS Request Monitor'[Date_Time] )

    )

Any ideas?

Hi  @Anonymous ,

According to the description of the error message, this is a circular dependency problem, when two object columns A, B depend on each other, when calculating A, it depends on B, but when calculating B, it needs to depend on A, then the engine does not know which object to calculate first.

You can check the following to understand and avoid circular dependencies:
