copy selected columns in a row to another sheet if a cell meets a condition - excel

Question

(not in a range, not adjacent columns)
(in given order)
I have many rows on Sheet1. I would like to copy some columns of a row (not the entire row and not a range of columns) to Sheet2 (to the first empty row of Sheet2) if a cell satisfies a condition (the cell in the current row and A column has a value of y)
I would like to copy not the entire row from Sheet1 only the row with those columns that are given on Sheet3 (Column A), and the new column number (on Sheet2) is also given on Sheet3 (column B)
It would be simple if my task would be to copy the entire row, or the selected column would be in a range...but i would need to copy those columns that are specialized on Sheet3. I would be grateful for any help. Thanks in advance.
Sheet1 shows an example data sheet. The criteria is if Cells(Rows, 1).Value = "y"
Sheet2 shows the desired result.
Sheet3 shows the selected column number on Sheet1 and the new column number on Sheet2

Answer 1

Whilst this probably should be done using arrays more, here's some basic VBA code that loops the first sheet checking for "y" in the first column. When it finds it, it then loops the column mappings in the third sheet that have been saved into arrays to set the values on the second sheet:
Sub sTranasferData()
On Error GoTo E_Handle
Dim aOld() As Variant
Dim aNew() As Variant
Dim wsIn As Worksheet
Dim wsOut As Worksheet
Dim wsTrack As Worksheet
Dim lngLastRow As Long
Dim lngLoop1 As Long
Dim lngLoop2 As Long
Dim lngRow As Long
Dim lngTrack As Long
Set wsIn = Worksheets("Sheet1")
Set wsOut = Worksheets("Sheet2")
Set wsTrack = Worksheets("Sheet3")
lngLastRow = wsIn.Cells(wsIn.Rows.Count, "A").End(xlUp).Row
lngTrack = wsTrack.Cells(wsTrack.Rows.Count, "A").End(xlUp).Row
aOld() = wsTrack.Range("A2:A" & lngTrack).Value
aNew() = wsTrack.Range("B2:B" & lngTrack).Value
lngRow = 1
For lngLoop1 = 2 To lngLastRow
If wsIn.Cells(lngLoop1, 1) = "y" Then
For lngLoop2 = LBound(aOld) To UBound(aOld)
wsOut.Cells(lngRow, aNew(lngLoop2, 1)) = wsIn.Cells(lngLoop1, aOld(lngLoop2, 1))
Next lngLoop2
lngRow = lngRow + 1
End If
Next lngLoop1
sExit:
On Error Resume Next
Set wsIn = Nothing
Set wsOut = Nothing
Set wsTrack = Nothing
Exit Sub
E_Handle:
MsgBox Err.Description & vbCrLf & vbCrLf & "sTransferData", vbOKOnly + vbCritical, "Error: " & Err.Number
Resume sExit
End Sub
