Choosing corresponding value from particular column based on given criteria

screenshot_data.JPG
I have the above model in my Power BI Desktop file and I am trying to do the following -

I have calculated the Version where the cummulative_version_adoption reaches atleast 50 percent for the first time(>=0.5) through the following measure.
Version_Rolled_Down = CALCULATE(LASTNONBLANK(Query1[Version],1),Query1[cummulative_version_adoption]>=0.5)
which gives me 97333.

Similarly, I am trying to calculate the Version_release_date of the Version where the cummulative_version_adoption reaches atleast 50 percent for the first time i.e., (>=0.5). If the corresponding version has date, then it needs to return that date or else "Date NA".
So from above, I would be picking up 13/08/2014.
But I am not able to do so for the dates as you can see I do not have dates available for every version and also lastnonblank requires me to have all the dates for the versions and also them to be in proper descending order.

It would be really helpful if someone can help me out on this.
Thank You.

Regards,

Sudhamshu

Perhaps something along these lines:

 

MyDate = VAR VersionNum = CALCULATE(LASTNONBLANK(Query1[Version],1),Query1[cummulative_version_adoption]>=0.5)

VAR VersionDate = CALCULATE(MIN([Version_Release_Date]),Query1[Version] = VersionNum)

RETURN

IF(ISBLANK(VersionDate),"Date NA",VersionNum)

This assumes that Version_Release_Date is text, if it is an actual DATE value you will probably have to convert it to the text representation of the date. You can do that with a CONCATENATE of the Version_Release_Date and "".

Hi @sg10,

 

As smoupre said, you cannot sombine a text value ("Date NA") and a date type value in a single result. But you could replace "NA" with Blank() if the corresponding version has no release date.

 

MyDate measure =
VAR VersionNum =
    CALCULATE (
        LASTNONBLANK ( Query1[Version], 1 ),
        Query1[cummulative_version_adoption] >= 0.5
    )
VAR VersionDate =
    CALCULATE ( MIN ( [Version_Release_Date] ), Query1[Version] = VersionNum )
RETURN
    IF ( ISBLANK ( VersionDate ), BLANK (), VersionDate )
