Difference between two variable data

Hi, Anonymous 

Based on your description, I have created many measures to achieve the effect you are looking for. Following picture shows the effect of the display.

Measure:

Diff =

VAR _version1 =

    SELECTEDVALUE ( Version1[Version1] )

VAR _version2 =

    SELECTEDVALUE ( Version2[Version2] )

VAR _version1Value =

    CALCULATE (

        MAX ( 'Table'[X] ),

        FILTER ( 'Table', 'Table'[Version] = _version1 )

    )

VAR _version2Value =

    CALCULATE (

        MAX ( 'Table'[X] ),

        FILTER ( 'Table', 'Table'[Version] = _version2 )

    )

RETURN

    IF (

        _version1Value >= _version2Value,

        _version1Value - _version2Value,

        _version2Value - _version1Value

    )

If this does not work, could you please share some sample data without sensitive information and expected output.
