Filter Table based on measure not working correctly - Dates

[SSBTexas]

I'm trying to determine why my date measure used to filter a table is not working.  

I have created a measure called PriorMonthStart.   Its value is calculated and is shown as 07/01/2021.   All set... looks good.  

Then I am counting the number of rows for a date equal to greater than the PriorMonthStart in this dataset:

MonHiresCount = CALCULATE(

COUNTROWS(EMP_HIRES),

FILTER(EMP_HIRES, EMP_HIRES[HIRE_DATE] >= [PriorMonthStart]))

The value of MonHiresCount = 9 whereas it should be 1.   

If I change the MonHiresCount Measure to: 

MonHiresCount = CALCULATE(

COUNTROWS(EMP_HIRES),

FILTER(EMP_HIRES, EMP_HIRES[HIRE_DATE] >= Date(YEAR([PriorMonthStart]),7,1)))   

I get the correct value of 1.  

If I try the MonHiresCount Measure to: 

MonHiresCount = CALCULATE(

COUNTROWS(EMP_HIRES),

FILTER(EMP_HIRES, EMP_HIRES[HIRE_DATE] >= Date(YEAR([PriorMonthStart]),MONTH([PriorMonthStart]),1)))   

It reverts back to being wrong again.  MonHiresCount = 9  

I even created another measure called Month-PriorMonth

MonHiresCount = CALCULATE(

COUNTROWS(EMP_HIRES),

FILTER(EMP_HIRES, EMP_HIRES[HIRE_DATE] >= Date(YEAR([PriorMonthStart]),[Month-PriorMonth],1)))   and the result is still 9.  

It seems like it it somehow reverting the month value from 7 to 6.  

The kicker???   It's working correctly with last months file (no changes in format)

AND with this month's file it has no issues in being used for a different calculation and producing correct results.  

MonTermsCount = CALCULATE(

COUNTROWS(EMP_TERMS),

FILTER(EMP_TERMS,EMP_TERMS[TERM_DATE] >= [PriorMonthStart]))

Any ideas?

Hi @SSBTexas ,

Not sure what is [DataThurMonth],is it a measure?Is it a fixed value?Will it cause a context problem?

Here I made a simple sample according to your data and using value of "today()" instead:

PriorMonthStart = DATE(YEAR(TODAY()),MONTH(TODAY())-1,1)

MonHiresCount = CALCULATE(
COUNTROWS('Table'),
FILTER(ALL('Table'), 'Table'[Hire_Date] >= [PriorMonthStart]))

And you will see:

Check my sample .pbix file attached for reference.

Best Regards,

@SSBTexas The issue is likely related to your PriorMonthStart and is also likely a context issue. It's hard to really know though without sample data, etc. Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
