PowerBI Date Manipulation

[sclement]

Hi All,

I am currently generating a report about purchase details on daily basis. I would like to get yesterday's purchase details till today 5 PM and after 5 PM, the report should show today's purchase details. 

Is there a way to implement this in PowerBI report?

Thanks in advance!

Hi, @sclement 
There is a NOW() function, that returns the current day and time.
If it's a measure, the time is refreshed upon refreshing the page (when published).
If it's a calculated column, the time is refreshed only upon refreshing the whole report.

I designed a measure and calculated column that would fit your needs:
Measure:

NowMeasure = 
var currentDay = TODAY()
var previousDay_ = currentDay-1

var CurrentDayFromTable = MAXX(FILTER(DatetimeAmount, DatetimeAmount[Date] = currentDay), DatetimeAmount[Date])
var PreviousDayFromTable = MAXX(FILTER(DatetimeAmount, DatetimeAmount[Date] = previousDay_), DatetimeAmount[Date])

var check = IF(DATEVALUE(NOW()) = currentDay && HOUR(NOW()) <= 16 && MINUTE(NOW())<=59, PreviousDayFromTable, CurrentDayFromTable)
return check

Column:

Column = 
var CurrentRowDate = DatetimeAmount[Date]
return IF([NowMeasure]=CurrentRowDate, 1, 0)

 It works as you described it:

The only drawback is that you would have to refresh your repot at 5 PM and then 12AM the next day.
So far I couldn'T come up with a better solution.

EDIT: 
You also have to then put a filter to your visualization and display only rows that equal 1.

Hi @vojtechsima ,

Sorry for the confusion.

I am using a matrix visualzation in the report and currently my visualization shows similar data as follows:

But I would like to have visualization to show below data when I am looking at the report before 5 PM on 13th April 2022.

 and If I am looking at the report after 5 PM on 13th April 2022, the report should display as follows:

I am not sure whether this has to be implemented with a measure or in power query. So please help.

Thank you for the heads up!

That's a great solution @vojtechsima. Thank you very much for sharing this with me.

Since I am using Direct query to fetch the data from database (this is because I have large dataset in our company's database) into visualisation, I have difficulities with this DAX functions that you have used in the measure. Do you think perhaps I can implement similar approach for direct query data fetching as well?

PS: Apologies for asking too many questions as I am a newbie to this area in PowerBi. 

Thank you!

Hi, @sclement 

According to your description, I think you can create a meaure and use it in visual filter pane to filter data.

Like this:

Measure 2 = 
IF (
    DATEVALUE ( NOW () ) = TODAY ()
        && HOUR ( NOW () ) <= 16
        && MINUTE ( NOW () ) <= 59,
    IF ( SELECTEDVALUE('Table'[Date]) = TODAY () ||SELECTEDVALUE('Table'[Date]) = TODAY () - 1, 1 ),
    IF ( SELECTEDVALUE('Table'[Date]) = TODAY (), 1 )
)

Did I answer your question? Please mark my reply as solution. Thank you very much.
If not, please feel free to ask me.

Hi, @sclement 
It's definitely possible, I just wonder about the result, could you please share a snippet of your desired output?
Should it be two measures?
One that shows today's till 5PM and second about yesterday's (whole day). 
Your initial request confuses me a bit. Thank you
