Latest available value

I have a table with WorkDate, Name and Initials.

Using a calculated column, I'm trying to obtain the Initials registered on the last available date for every Name.

This is the expected result:

I tried this but it's giving me an "out of memory"

Initials 2 =
LOOKUPVALUE (
    Table[Initials],
    Table[WorkDate],
        CALCULATE (
            MAX ( Table[WorkDate] ),
            FILTER (
                Table,
                Table[Name] = EARLIER ( Planday[Name] )
                    && Table[WorkDate] < EARLIER ( Table[WorkDate] )
            )
        )
)
