Filling Blank Dates Challange

Thanks for the reply from Ashish_Mathur and NaveenGandhi , please allow me to provide another insight:

Hi, PowerRobots99 

Regarding the issue you raised, my solution is as follows:

1.First I have created the following table and the column names and data are the data you have given:

2. Below are the measure I've created for your needs:

 

MEASURE =
VAR cc =
    MAX ( 'Table'[Dates] )
VAR bb =
    CALCULATE (
        MAX ( 'Table'[ReportDate] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[PO] = MAX ( 'Table'[PO] )
                && 'Table'[ReportDate] < MAX ( 'Table'[ReportDate] )
        )
    )
VAR aa =
    CALCULATE (
        MAX ( 'Table'[Dates] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[PO] = MAX ( 'Table'[PO] )
                && 'Table'[ReportDate] = bb
        )
    )
RETURN
    IF ( ISBLANK ( cc ), aa, cc )

 

3.Here's my final result, which I hope meets your requirements.

Please find the attached pbix relevant to the case.
