Moving Target Sum

Hi community. Im trying to replicate an excel calculation from a colleague. Basically he created this measure that aims to predict revenue stream for upcoming months. I do not agree with this method but my only task is replicating this in Bi. I will explain everything below as I feel it's easier shown than written.

Basically I have data in the way thats shown below:

TABLE A	A	B	C
1	Year	Month	Revenue
2	2021	1	100
3	2021	2	102
4	2021	3	101
5	2021	4	122
6	2021	5	100
7	2021	6	123
8	2021	7	100
9	2021	8	105
10	2021	9	130
11	2021	10	115
12	2021	11	115
13	2021	12	162
14	2021	1	123
15	2021	2	121
16	2021	3	100

I need to create a measure that calculates a new column, lets call it D, that will have information sort of like this:

TABLE A	A	B	C	D
1	Year	Month	Revenue	New Measure
2	2021	1	100	+SUM(C3:C14)
3	2021	2	102	+SUM(C4:C15)
4	2021	3	101	+SUM(C5:C16)
5	2021	4	122	...
6	2021	5	100
7	2021	6	123
8	2021	7	100
9	2021	8	105
10	2021	9	130
11	2021	10	115
12	2021	11	115
13	2021	12	162
14	2021	1	123
15	2021	2	121
16	2021	3	100

Any ideas on hwo to calculate this new measure in PBi?

Thanks!

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.
