Hello,

I think that it can be improved but the following expression can solve your issue..
Gallery1.Items = ForAll(Distinct(A,Value),LookUp(A,Id=Min(Filter(A,Value=Result),Id)))

Here is a suggestion that only requires reading the source table once:

 

AddColumns(
    GroupBy(
        SourceTable,
        "Value",
        "AllRows"
        ),
    "MinId",
    Min(AllRows, Id)
    )

 The result will contain the AllRows column, but this can be ignored.

I think Meneghino's solution is better. You should use that one.
You can use the DropColumns() function to get rid of the AllRows column if you want to.
