Dynamicaly Filtered Calculated Table

Hi johmedrano,

You can try to use below formula to find out last update date of each partner:

Last Update =
CALCULATE (
    MAX (
        Table[Date],
        FILTER (
            ALLSELECTED ( Table ),
            Table[Partner Name] = SELECTEDVALUE ( Table[Partner Name] )
        )
    )
)
