Union filter in Power Query or DAX

Hello, I have a very simple filtering task (conceptually). But can't figure out how to apply combined filter to a very simple dataset.   Original dataset   Item                                 ...

    What about something like this?

    So Items 1 and 6 have all ABC, but item 3 does not since ABC happened in one row, but if that needs to be accounted for can change the code easily. 

    ALL ABC Check = 
var __CurrentID= Table1[Item]
RETURN

Var __NewColumn=
CALCULATE(
    CONCATENATEX(
        'Table1',
        'Table1'[Added by]),
        FILTER(
            'Table1',
            Table1[Item] = __CurrentID
        )
)
RETURN

IF(
    AND(
        LEN(Table1[Added by]) =1,
        SEARCH("A",__NewColumn,,0)+SEARCH("B",__NewColumn,,0)+SEARCH("c",__NewColumn,,0) >= 3
    ),
    "ALL ABC",
    "Missing"
)

Thanks, however I'm afraid that this is not a solution I'm looking for.

This is a full code, which does exactly what I want.

But I still want to do it in DAX, but still can't figure out how.

I think that DAX solution would be much more elegant.

 

 

let
    Source = Table1,
    #"Filtered Rows" = Table.SelectRows(Source, each ([Added by] = "A" or [Added by] = "B" or [Added by] = "C")),
    #"Kept Duplicates" = let columnNames = {"Item"}, addCount = Table.Group(#"Filtered Rows", columnNames, {{"Count", Table.RowCount, type number}}), selectDuplicates = Table.SelectRows(addCount, each [Count] > 1), removeCount = Table.RemoveColumns(selectDuplicates, "Count") in Table.Join(#"Filtered Rows", columnNames, removeCount, columnNames, JoinKind.Inner)
in
    #"Kept Duplicates"

    I will not pretend that I fully understand this DAX, but it works perfectly and I can easily modify it for production cases.

    This is good, since I do not need to reload rather big sources and filter it in a fraction of second, unlike my Power Query or Pandas solutions. 

    Thanks!
