Vlookup - PowerBI - Text range or list

Hi jaimemagana ,

You can convert the text to UniCode and then compare them.
1. First add a new column to table.

NumberCode = 
UNICODE ( 'Table'[3Letters] ) * 10000
    + UNICODE ( MID ( 'Table'[3Letters], 2, 1 ) ) * 100
    + UNICODE ( RIGHT ( 'Table'[3Letters] ) )

2. Then create the column in plate table.

Lookup = 
VAR Fir = UNICODE ( [3Letters] )
VAR Sec = UNICODE ( MID ( [3Letters], 2, 1 ) )
VAR Thir = UNICODE ( RIGHT ( [3Letters] ) )
VAR PlateUnicode = Fir * 10000 + Sec * 100 + Thir
VAR Tab =
    FILTER (
        'Table',
        'Table'[NumberCode]
            = MAXX ( FILTER ( 'Table', [NumberCode] <= PlateUnicode ), [NumberCode] )
    )
RETURN
    MAXX ( Tab, [Attribute] ) & " " & MAXX ( tab, [Year] )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
