Help Need DAX row count between dates

[wolfsvein]

=CALCULATE(COUNTROWS(Fact_SalesSummaries),
     DATESINPERIOD(Fact_SalesSummaries[BidWonDate],
         LASTDATE(Fact_SalesSummaries[BidWonDate]),
         -3, MONTH),
     Fact_SalesSummaries[BidWonDate] <> BLANK())

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

I am trying to do this in a tabular model in SSAS I have tried with a calendar and without a calendar table but everything I have read says this should work but the issue is that they alway calculate to 1 and not a some of prior 2 months and current month.

I'm not good with SQL, so i want understand what you need.
Do you need retrieve the number of rows where:
1. Start 03 month back and finish the last date previous the current date.
2. BidWonDate <> Blank.

Yeah? Or did I change everything? haha

[wolfsvein]

SO what is needed is a rolling 3 month count of records between prior 3 months and current date, and the records are not blank().

I even tried does this in a measure.

calculate(countrows(date), datesbetwween(date[field], eomonth(lastdate(date[field]),-4)+1, eomonth(lastdate[date[field],0)))

Hi @wolfsvein,

Can you share a sample please? You can mask the data first. 

It seems the formula is a calculated column. How about using it as a measure?

Best Regards,

I created this random data generated SQL so it give you a sample data set to work with. Run this in TSQL and create a physical table then you can import in Excel or PowerBI to work with the DAX syntax.

The SQL example show what the date example and I am putting in a measure.
