Moving Target Sum

Hi, Anonymous 

May I ask if this is the expected output you are looking for? Based on your description, I have created a measure to achieve the effect you are looking for. Following picture shows the effect of the display.

Measures:

PredictedValue =

VAR _1 =

    SUM ( 'Table'[Index] ) + 1

VAR _2 =

    SUM ( 'Table'[Index] ) + 12

VAR _predictedValue =

    CALCULATE (

        SUM ( 'Table'[Revenue] ),

        FILTER ( ALL ( 'Table' ), 'Table'[Index] = _1 || 'Table'[Index] = _2 )

    )

RETURN

    _predictedValue

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