Find all duplicates in a column of a certain value and return values from the next column

Question

I am trying to make something that would look like this:

In the table on the right there will be all the unique records which will be stored in a certain area. However some record may be existing in more areas, and this information can be taken from the list in column A and B. The macro should take each unique record in column D and search for it in Column A, every time it finds it, should copy the location/area in column B and pasted next to the unique record in the table. I think I could do this with a loop, but what I created in the code below does not really works.

The second challenge is to make it understand that in a location has been copy into the table, the new found location needs to be pasted in the next free cell of that same unique record.

I am aware my code is a little scare but I would appreciate even just advice on which direction I should be looking... Thanks in advance!

    Dim UC As Variant, UCrng As Range, ra As Range

    Set UCrng = Range("F2:F6")

    For Each UC In UCrng

        Set ra = Cells.Find(What:=UC, LookIn:=xlFormulas, _
        LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
        MatchCase:=False, SearchFormat:=False).Activate

        ra.Offset(0, 1).Copy Destination:=Range("E2")

    Next

End Sub

Answer 1

I would suggest looping through all Rows (Columns A + B), e.g.:

For i = 1 to Rows.Count
'DoStuff
Next i

For each row, you copy the value of A into D, if it is not there already. You can access the values like this:

Cells(i, "A").Value
Cells(i, "B").Value

For finding values in a column, see here. If you found a duplicate, use another loop to check which column (E, F, G,..) in your specific row is the first empty one, and past the value of column B there.

Take a try:

Option Explicit

Sub test()

    Dim LastRowA As Long, LastRowD As Long, i As Long, rngColumn As Long
    Dim rng As Range

    With ThisWorkbook.Worksheets("Sheet1")

        LastRowD = .Cells(.Rows.Count, "D").End(xlUp).Row

        .Range("D2:J" & LastRowD).ClearContents

        LastRowA = .Cells(.Rows.Count, "A").End(xlUp).Row

        For i = 2 To LastRowA

            LastRowD = .Cells(.Rows.Count, "D").End(xlUp).Row

            Set rng = .Range("D1:D" & LastRowD).Find(.Range("A" & i).Value, LookIn:=xlValues, lookat:=xlWhole)

            If Not rng Is Nothing Then
                rngColumn = .Cells(rng.Row, .Columns.Count).End(xlToLeft).Column
                Cells(rng.Row, rngColumn + 1).Value = .Range("B" & i).Value
            Else
                .Range("D" & LastRowD + 1).Value = .Range("A" & i).Value
                .Range("E" & LastRowD + 1).Value = .Range("B" & i).Value
            End If

        Next i

    End With

End Sub

I think this code will do what you want. Please try it.
