Custom forward projection

[Anonymous]

Hi All,

I have a table as shown below. FY and Qtr are derived from a [Dates] table. The values in Red are projected. Each projected value is based on the previous one (previous quarter). The black ones are observed values so 3377 is 3396 + X (X being a calculation based on a sum of parameters), 3368 is 3377 + X, and so on.

My [Dates] table has dates up to 2025 so I'd like to run that projection for all those dates.

FY	Qtr	Value
FY20	Q1	1186
FY20	Q2	3087
FY20	Q3	3310
FY20	Q4	3780
FY21	Q1	3717
FY21	Q2	3396
FY21	Q3	3377
FY21	Q4	3368

Could someone help me with that or point me to an article?

Many thanks!

@Anonymous , What you do is take max QTR Value and then take diff in Qtr and Multiple parameters with that

3396 +X

3396+ 2X

Have a column 

QTR in YYYYQ  format

and qtr rank column

Qtr Rank = RANKX(all('Date'),'Date'[QTR Rank],,ASC,Dense)

Measure  =

Var _max = Maxx(allselected(Table), Table[Qtr Rank]) // Have Year qtr in YYYYQQ format

var _maxVal = maxx(filter(allselected(Table), Table[Qtr Rank] = _max), Table[Value])

return

_maxVal +(2* max(Table[Qtr Rank])  -_max)

@amitchandak Thanks a lot for that quick response! I'm a bit confused though...

I don't understand the "3396 + 2X" part and the DAX formula. Could you elaborate?

Maybe I should provide clarity:

First projected value is = previous value + X

Second projected value is = first projected value + Y

Third projected value is = second projected value + Z...

X, Y and Z are calculations that are also date related.

I have a Date table ready that is providing the Quarter value from a proper date

So I guess I could work with time intelligence rather that RANK, right?

Hi @Anonymous ,

I created a sample measure for calculating the value of time-based variables: X, Y, Z...

test parameters = QUARTER(MAX(Dates[Date]))*100

Then create measures:

Sum_Parameters = 
IF(
    COUNTROWS(Dates) = COUNTROWS( ALLSELECTED(Dates) ),
    SUMX(
        SUMMARIZE(
            'Dates',
            Dates[FY],
            Dates[Qtr],
            "_sum",
            [test parameters]
        ),
        [_sum]
    ),
    [test parameters]
)

Measure = 
var Last_Date = MAXX(ALL('Table'),'Table'[Date])
var QuarterEnd = 
    CALCULATE(
        VALUES('Table'[Date]),
        ENDOFQUARTER('Table'[Date])
    )
var FactValue = SUM('Table'[Value])
var ProjectedValue = 
    CALCULATE(
        SUM('Table'[Value]),
        FILTER(
            ALL(Dates),
            Dates[Date].[Year] = YEAR(Last_Date)
            && Dates[Date].[QuarterNo] = QUARTER(Last_Date)
        )
    ) +
    CALCULATE(
        [Sum_Parameters],
        FILTER(
            ALL(Dates),
            Dates[Date] > Last_Date
            && Dates[Date] <= MAX(Dates[Date])
        )
    )
return 
    IF(
        MAX(Dates[Date]) > QuarterEnd,
        ProjectedValue,
        FactValue
    )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
