Moving Average for custom calendar

[Anonymous]

Hey everyone, 

I have  a custom calendar so the moving average calculations I have tried aren't working, namely the DATESINPERIOD function. My Calendar periods are 28 days each and the financial year begins on the 1/04/17 for eg. Is there a way I can use the DATESINPERIOD function and format it to begin at the start of my financial year, or is there any other way around calculating moving average for a custom calendar.

Thank you in advance 

Regards,

Hi @Anonymous,

I'm afraid this is not available. Such a time intelligence function works based on natural calendar dates, instead of custom calendar.

or is there any other way around calculating moving average for a custom calendar.

I solved it, thanks for your prompt reply though

In case anyone else needs a pointer in how to achieve this;

Index your months in your calendar table 

and then filter using your calendar date table and calendar index column

max<= (x) - how many steps, or months, [n-1) logic, so for 3 months = max <= -2 and for 12 months = max<= -11

Then create a new measure, which will allow you to divide by the periods you have, so eg, in  12 month Fiscal Year, I have 13 periods, so I use my index measurement and divide it by 13 periods
