Difference between two points

Hi Guys,

 

I have data that is not transactional. Each entry is the current value for that month. Thus it's not data such as sales that can be summed but rather a single value at a point in time.

My objective is to determine the difference between the value for this month and six months prior. All the examples use a variation of this Datesbetween formula:

 

Delta =
CALCULATE(sum(Sales[Monthly Sales]),
DATESBETWEEN('Calendar'[Date],
Max('Calendar'[Date]) - 180,
Max('Calendar'[Date])))
 
This doesn't work as I don't 'Sum' my data. See the image below:

I just want to do simple math and determine 2000 (From this month) - 2500 (From 6 months ago) = -500. Can't get it right at all!
 
Thanks

Re: Difference between two points

You could try something like 

CALCULATE(

                    SUM(

                             Sales[Monthly Sales]

                            )

                    )

-

CALCULATE(

                    SUM(

                             Sales[Monthly Sales]),

                    FILTER(

                               ALL('Calendar'), 

                               'Calendar'[Date]=Max('Calendar'[Date]) - 180

                               )

                   )

Re: Difference between two points

It's still returning the whole table. I want a scalar value returned. Surely there should be a simple way to do calculations like this in PowerBI

Hi @JBI ,

For your requirement, you could refer to the measure below. You could modify it based on your scenario.

Measure =
VAR c_m =
    CALCULATE (
        SUM ( 'Sales'[Project Sales] ),
        FILTER (
            'Calendar',
            'Calendar'[Month] = MAX ( 'Sales'[Month] )
                && 'Calendar'[Date].[Year] = MAX ( 'Sales'[year] )
        )
    )
VAR c_m_6 =
    CALCULATE (
        SUM ( 'Sales'[Project Sales] ),
        DATEADD ( 'Sales'[Date_column], -6, MONTH )
    )
RETURN
    c_m - c_m_6

Here is the output.
