Get single value using VAR from multiple value options

Hi Anonymous ,

According to your description, here are my steps you can follow as a solution.

(1) This is my test data.  

(2) We can create a calculated column.

GR Date =
VAR _a =
    LOOKUPVALUE (
        'GR - 5G SvC_master ~ 2022 - Previous Backup Data'[GR Date],
        'GR - 5G SvC_master ~ 2022 - Previous Backup Data'[Site], [Internal Site ID]
    )
VAR _max_index =
    CALCULATE (
        MAX ( 'GR - 5G SvC_master since 2023 - Current Monthly Data'[Index] ),
        FILTER (
            'GR - 5G SvC_master since 2023 - Current Monthly Data',
            [Site] = EARLIER ( 'Distinct - Master Data'[Internal Site ID] )
        )
    )
VAR _b =
    CALCULATE (
        MAX ( 'GR - 5G SvC_master since 2023 - Current Monthly Data'[GR Date] ),
        FILTER (
            'GR - 5G SvC_master since 2023 - Current Monthly Data',
            [Site] = EARLIER ( 'Distinct - Master Data'[Internal Site ID] )
                && [Index] = _max_index
        )
    )
RETURN
    IF ( ISBLANK ( _a ), _b, _a )

(3) Then the result is as follows.
