Re: Calculate Rolling Average for 2 years data

Here you go :

// Your parameters

Let vNbMonthsToLetAsItIs=6;

let vNbOfMonthsToTakeInAvg=6;

// Your data load

Temp_Data1:

LOAD

    "Month" as Period,

    Cost

FROM [lib://CommunityTests/RollingAvg.xlsx]

(ooxml, embedded labels, table is Feuil1);

// Rest of script

Temp_Data2:

LOAD

recno() as PeriodID,

Period,

Cost

resident Temp_Data1

order by Period;

join(Temp_Data2)

LOAD

recno() as PeriodID_2,

Cost as Cost_2

resident Temp_Data1

order by Period;

Drop table Temp_Data1;

NoConcatenate

Temp_Data3:

LOAD

*

resident Temp_Data2

where PeriodID>=PeriodID_2-$(vNbOfMonthsToTakeInAvg) and PeriodID<=PeriodID_2;

Drop table Temp_Data2;

NoConcatenate

Final:

Load

avg(Cost) as Cost,

Max(Period) as Period,

PeriodID_2

resident Temp_Data3

where if(PeriodID_2<=$(vNbMonthsToLetAsItIs),PeriodID_2=PeriodID,1=1)

group by PeriodID_2;

Drop table Temp_Data3;

Re: Calculate Rolling Average for 2 years data

Hi Thomas,

Thanks for the reply. While trying the above code, it's getting hanged. Is there any other way to do so?
