Calculate value for a specific month

[ithomas2]

Hi,

I'm pretty new to power bi and am trying to get a value for the baseline of a kpi. I have a measure for calcualting the average number of issues on a document. There are lots of documents each month. I can use a card and a month filter on the report to show the average number of issues in Jan 2020. I'd like to know how I can "record" or calculate this as a number that can be used in a kpi. For instance, my kpi is likely to be a 20% reduction in issues from Jan to Dec 2020. Thanks for any help you can provide.

Hi @ithomas2 ,

We can use the following steps to meet your requirement.

1. We can create a month column.

Month = MONTH(‘Table’[Date])

2. Then we can create a two measures, one is the average of each month based on the month slicer, another is the average of end of year month.

And we can put them to a KPI card, the result like this,

select month AVG = 
CALCULATE(AVERAGE('Table'[value]))

End of year AVG = CALCULATE(AVERAGE('Table'[value]),'Table'[Month] = 12)

If it doesn’t meet your requirement, could you please show the exact expected result based on the table that we have shared?

BTW, pbix as attached.

@ithomas2 you need to create a measure for Previous month which can be achieved by using Time Intelligence DAX functions. As a best practice, add date dimension in your model and use it for and time intelligence calculations. There are many posts on how to add date dimension and below is the link to a few. Once the date dimension is added, mark it as a date table on table tools.

Once you had date dimension in your model, use PREVIOUSMONTH DAX function and that you can use KPIs to calculate the % difference.
