parallelperiod vs previousmonth vs adddate

Hi All,   I found a solution to this already but am confused about why it is so.     I need to find a simple previous month lookup.     Prev. Month Sales = CALCULATE(SUM([Total Sales]),DATEADD(...

    Hi SHDJason,

     

    In DAX, PARALLELPERIOD always returns full periods at the given granularity level instead of the partial periods that DATEADD returns. So please check if the dates in date column are continuous. If the dates in the current context do not form a contiguous interval, the function returns an error.

     

    Reference:
    PARALLELPERIOD Function (DAX)

Hi SamiTi,

 

Thanks for replying. I don't really understand what you suggest me to try though, sorry.

Here's a screenshot of what my report looks like until now.

 

I don't want to have to apply a filter myself because my intention is to publish this report in the Power BI service and other users will daily consult it. So it has to calculate last month sales itself without my intervention.

 

Thanks again

Ben

Hi Ben

 

Add a slicer with  month year in order for measure to return Previous month value. 

 

User will need to select Month from Slicer.
