I have tried search and different ways to counts rows that have dates between 2 different dates it calculates the rows as 1 and not more than that in the formula.
This is meant to be a rolling 3-month count of records from date back 3 months to be able to calculate an average with a count of all records.
Example in SQL would look like this.
select MonthBlended, yearblended, BidWonDate, BidWonFlag,
(select count(*) from Fact_SalesSummaries
where convert(date, cast(MonthBlended as varchar(2))+ '/01/' + cast(YearBlended as varchar(4)), 101) between
dateadd(mm, -3, convert(date, cast(t1.MonthBlended as varchar(2))+ '/01/' + cast(t1.YearBlended as varchar(4)), 101))
and convert(date, cast(t1.MonthBlended as varchar(2))+ '/01/' + cast(t1.YearBlended as varchar(4)), 101)
and BidWonDate is not null
) as CountWONPrior3Month,
(select count(*) from Fact_SalesSummaries
where convert(date, cast(MonthBlended as varchar(2))+ '/01/' + cast(YearBlended as varchar(4)), 101) between
dateadd(mm, -3, convert(date, cast(t1.MonthBlended as varchar(2))+ '/01/' + cast(t1.YearBlended as varchar(4)), 101))
and convert(date, cast(t1.MonthBlended as varchar(2))+ '/01/' + cast(t1.YearBlended as varchar(4)), 101)
) as CountALLPrior3Month
from Fact_SalesSummaries t1
BidWonDate BidWon CountWonPrior3Month CountAllPrior3Month

Well trying this in a measure does work but does not calculate correctly any help would be greatly appreciated.
I included a sql script that will give you a random data sample that will match the data I have. Run the script and it will generate a random dates or nulls that you can run the dax expression against. Thanks for any help.

Answer 1

I'm new to DAX and PowerBI,
as i've understood the calculate function, i think your second parameter is what's causing u the error, the second param must be a filter, you are not fitering anything in your case, you are just returning a range of dates,
i'm really trying to be helful even know i might be getting it wrong, anyway wouldnt hurt if you try it :D

Answer 2

Counting the number of records from the current date going back 3 months can be done with the following measure.
enumerator =
CALCULATE (
COUNTROWS ( Fact_SalesSummaries ),
DATESINPERIOD (
'Fact_SalesSummaries'[BidDateWon],
LASTDATE ( 'Fact_SalesSummaries'[BidDateWon] ),
3,
MONTH
),
Fact_SalesSummaries[BidDateWon] <> BLANK ()
)
The fact your lost bids dont have dates makes it difficult to get this accurate, because you have to rely on the ordinal (and hopefully contiguous) numbering of the ID's to create the denominator.
denominator =
CALCULATE (
MAX ( Fact_SalesSummaries[ID] ) - MIN ( Fact_SalesSummaries[ID] )
+ 1,
DATESINPERIOD (
'Fact_SalesSummaries'[BidDateWon],
LASTDATE ( 'Fact_SalesSummaries'[BidDateWon] ),
-3,
MONTH
)
)
If you had dates in the rows where the bidwon=false, you could use the same calclation as the enumerator, just removing the last filter.
