EXACTLY WHAT I AM TRYING TO ACCOMPLISH: (Forecast Lines)

========
Hello Productive People!

I need some help. I am trying to write some DAX code that will draw a flat forecasted line from "Today" to "FutureDate". However, something weird is happening. When I HARD-CODE a date - it works. But when I refer to a MEASURE that has a date-value, it doesn't work.

Can someone take a peek and see if anything jumps out?

Also, I am still learning DAX & PowerBI - so please feel free to critique my approach if there is a better method.

RETURN
//THIS CODE WORKS - WHAT I WANT
if( 
    ISBLANK(
        COUNTROWS(
            Filter(
                'DATE',
                'DATE'[Date] >= TODAY() && 'DATE'[Date] <= DATE(2023,08,27)
            )
        )
    ),BLANK(),lastval 
)

// THIS CODE DOES NOT WORK

VAR projDate = [Release BD - Projected Completion Date (1)] 
RETURN
if( 
    ISBLANK(
        COUNTROWS(
            Filter(
                'DATE',
                'DATE'[Date] >= TODAY() && 'DATE'[Date] <=  projDate
            )
        )
    ),BLANK(),lastval 
)

Release BD - Projected Completion Date (1) = 
VAR daysUntilCompletion = [Release BD - Active Story Points]/[Release BD - Daily Story Point Velocity]
RETURN
if(
    [Release BD - Release End] > TODAY(),TODAY()+daysUntilCompletion,[Release BD - Release End]
)

Hi @FEninja_ ,

Please try this measure:

Measure = 
VAR projDate = [Release BD - Projected Completion Date (1)] 
RETURN
if( 
    ISBLANK(
        COUNTROWS(
            Filter(
                ALL('DATE'),
                'DATE'[Date] >= TODAY() && 'DATE'[Date] <=  projDate
            )
        )
    ),BLANK(),lastval 
)

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

Best Regards,

Neeko Tang

Thank you for your response! I updated my original post to include a sample PBIX file along with more clarity about what I hope to accomplish. Thanks for your help
