In March, value for Ankit Gupta is blank, I want to show 9 for March against Ankit Gupta as this is his previous month value.

Below is my backend data:

Please help

Hi, 

Thanks for the solution !

I am kind of facing with similar problem. In my case if the if a person does not have any hours recorded against him in any particular month his name is skipped from that month. To encounter the issue I have created two databases. First database contains all the months and second data contains all the names. These two databases are connected to the master sheet. Lets consider the master sheet same as what sandeep_Sharma has provided.

How can i write a DAX to overcome the issue ?

Hi @sandeep_sharma ,

Please try below steps:

1. below is my test table

Table:

2. create a measure with below dax formula

Measure =
VAR cur_name =
    SELECTEDVALUE ( 'Table'[Name] )
VAR cur_date =
    SELECTEDVALUE ( 'Table'[Date] )
VAR max_date =
    MAXX (
        FILTER ( ALL ( 'Table' ), 'Table'[Date] < cur_date && 'Table'[Name] = cur_name ),
        [Date]
    )
VAR _val =
    CALCULATE (
        MAX ( 'Table'[Hours Spent] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Date] = cur_date && 'Table'[Name] = cur_name )
    )
VAR _val2 =
    CALCULATE (
        MAX ( 'Table'[Hours Spent] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Date] = max_date && 'Table'[Name] = cur_name )
    )
RETURN
    IF ( ISBLANK ( _val ), _val2, _val )

3. add a matrix visual with fields and measure

Please refer the attached .pbix file.

Would it be possible to also add the value of April for name B and C. For this case it would have the take the value of last available value which for this case would be Feb value.
