calculating last 30, 60 and 90 days

I am trying to calculate the number of records in a table that have occurred in the last 30 (60 and 90) days from a date selected on my slicer.  I have tried multiple formulas without success.  I have a date table also.

I would appreciate any advice.  Thanks

Hi @emmaclarke83

 

Try this MEASURE

 

RecordCount_Last30Days =
CALCULATE (
    COUNTROWS ( TableName ),
    DATESINPERIOD ( TableName[Date], SELECTEDVALUE ( TableName[Date] ), -30, DAY )
)

Please try my custom visuals

Hi

 

Sorry it doesn't seem to calculating properly.  I get the same result for 30, 60 and 90 days.  Any idea why?

Hi Emma!

 

This question has more then one solution.

1) A simple way to anterstand a calculation IMHO is create 3 new calculate rows in your Fact table with 3 dates (+30, +60 and +90 days from the current date).

 

2) Alternate way is a bit comlex, but more flexible (see link bellow):

  • I have one Date table, that I use as Fact table to (for this example only, in fact you must have separate fact table).
  • And I create new Slicer data table from 1 to 90 days (max. to 365!):
    • Days_Interval = GENERATESERIES(1;90)
      and rename "Values" to "Days". 
      And in your case  the formula above can be (for ex.): Days_Interval = GENERATESERIES(1;90;30), or list of discret values
  •  Then I create a measure:
    Max_Days_Value = 
    MAXX(
    	KEEPFILTERS(VALUES('Days_Interval'[Days]));
    	CALCULATE(MAX('Days_Interval'[Days]))
    )
  • Create slicer. It look like this:Date_Slicer(1).png

     

  • At last I use modyfied mohammad's expression (thanks @Zubair_Muhammad😞
    RecordCount_LastXDays = 
    CALCULATE (
        COUNTROWS ( Dates );
        DATESINPERIOD ( Dates[Dates]; FIRSTDATE( Dates[Dates] ); [Max_Days_Value];DAY)
    )
    of course instead "Dates" must be your Fact table.

This is example PBIX. Enjoy

Thanks for this.  Your link to the sample file is broken.  Can you repost?

It's really strange. I tested from another device and network. Must be OK.

But this is alternate LINK
