Distinct count for -6 to -12 months / -12 to -18 months

[Anonymous]

Evening,

Hoping not to difficult a question for some talented PowerBI Guru's.

I am trying to calculate the distinct count of orders for the last 6 months and the last 6(7) to 12 months, so that is a rolling figure and always the last 0 to 12 months in two seperate calculated measures but effectivly a rolling sum of orders for the last 12 months.

At the moment i have a measure for the previous Fiscal year like the below;

Orders in 2014 = CALCULATE(DISTINCTCOUNT('Table'[OrderColumn]), DATESBETWEEN('Table'[DateColumn], DATE(2013, 10, 01), DATE(2014, 09, 30)))

But thinking a rolling average would be better so it adapts as the market changes rather than basing targets on a static previous 3 years when the last 6/12 months is the most relevant to project the next 6 to 12 months.

Thanks in Advance,

J

This is what i have so far, but just returning a Null value...

Dist Orders Last 6 months = CALCULATE(DISTINCTCOUNT('Table'[OrderColumn]), DATESINPERIOD('Table'[DateColumn], TODAY(), "6",MONTH))

*Table and Column names changed*

Hoping im missing a () somewhere and nothing to major.

Thanks,

J

Think ive just cracked it...

Dist Orders Last 6 months = CALCULATE(DISTINCTCOUNT('Table'[OrderColumn]), DATESINPERIOD('Table'[DateColumn], TODAY(), -6, MONTH))

Added the - and remove the ""

Just validating the output now manually.

Thanks,

J
