Last Week comparison not working properly

[vijayvizzu]

Hi

I have created a measure to compare the current week value with last week value. Its working fine in some pages, but all.

X_Test_Measure = 

VAR _LW_Price = 
LASTNONBLANKVALUE(
        DATEADD(
            CalendarT[Date],
            -7,DAY
        ),
        [Total Value]
    )
VAR _CW_Price =
    LASTNONBLANKVALUE(
        CalendarT[Date],
        [Total Value]
    )
RETURN 
IF( ISBLANK( [Total Value]),BLANK(),_CW_Price-_LW_Price)

 Below matrix value shows me correct values, but when i am putting into a matrix visual as top level info it gives me blank.Unable to find out the error

Hi, @vijayvizzu 

There is a suitable context in the matrix so it is displayed correctly. Since your measure contains other measure, we can't judge why there is a blank based on the information you provide. If you can't provide data, I think you need to check whether the context and the measure are in harmony.

Hi @v-janeyg-msft  @amitchandak 

I understood the problem, unable to fix it

The problem is that, if the date selection ranges between weekly published dates, then it calculates the numbers correctly, but we selected the beyond that publish date, then it won works

Example,

I have the publish dates till 30th Jun 2021, in the date slicer, if i will select 7th Jul (greater than publish date), then it won't work because there was no values in that date range. So, how can i elimate the user to select the beyond the publish dates.

Hi, @vijayvizzu 

If you are talking about date slicer, then you can directly control the range of date selection on the filterpane to meet your needs.

@v-janeyg-msft 

Thanks for the suggestion, but how it can be dynamic ? I want to filter publish dated for a particular Source only, i have multiple sources in my main table.

Hi, @vijayvizzu (I took a long vacation due to illness)

I don't know your specific thoughts, but it should be possible.

You can create a measure and use it in filter pane to filter date dynamically like this:

@vijayvizzu , Make sure Cw_no is coming from the date table .

or

Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
