Excel macro to comparison of rows

I am trying to do below example, not able to do it.

Excel Data in Sheet1:

id     Sysid     option      status
XYZ      XT       Open       status_1
US     XT       Close      Status_1
US      XT       Open       Stauts_2
NJ      XT       Open   Status_2
IND     VX       Close      Status_1
BAN     VX       Open       Status_1
CHN     XY       Open       Status_1
YST     xy       Close      Status_1

In above data Status_1 and Sysid defines unique record,Based on this condition i have to find out which records have open and close difference for that unique record combination. If options are different I have to copy that data to different sheet using excel macro.This should work only for id's US and CHN.Suppose if id has US ,it shou开发者_Go百科ld compare with matching record based on sysid and Status. Any help appreciated.

Output Like below:

 XYZ      XT       Open       status_1
 US     XT       Close      Status_1
 CHN     XY       Open       Status_1
 YST     xy       Close      Status_1

Edited to include test for "US" or "CHN"

Sub Tester()

Const COL_ID As Integer = 1
Const COL_SYSID As Integer = 2
Const COL_STATUS As Integer = 4
Const COL_OPTION As Integer = 3
Const VAL_DIFF As String = "XXdifferentXX"

Dim d As Object, sKey As String, id As String
Dim rw As Range, opt As String, rngData As Range
Dim rngCopy As Range, goodId As Boolean
Dim FirstPass As Boolean, arr

    With Sheet1.Range("A1")
        Set rngData = .CurrentRegion.Offset(1).Resize( _
                         .CurrentRegion.Rows.Count - 1)
    End With
    Set rngCopy = Sheet1.Range("F2")

    Set d = CreateObject("scripting.dictionary")
    FirstPass = True

redo:
    For Each rw In rngData.Rows

        sKey = rw.Cells(COL_SYSID).Value & "<>" & _
               rw.Cells(COL_STATUS).Value

        If FirstPass Then
          'Figure out which combinations have different option values
          '  and at least one record with id=US or CHN
          id = rw.Cells(COL_ID).Value
          goodId = (id = "US" Or id = "CHN")
          opt = rw.Cells(COL_OPTION).Value

          If d.exists(sKey) Then
              arr = d(sKey) 'can't modify the array in situ...
              If arr(0) <> opt Then arr(0) = VAL_DIFF
              If goodId Then arr(1) = True
              d(sKey) = arr 'return [modified] array
          Else
              d.Add sKey, Array(opt, goodId)
          End If

        Else
          'Second pass - copy only rows with varying options
          '  and id=US or CHN
          If d(sKey)(0) = VAL_DIFF And d(sKey)(1) = True Then
              rw.Copy rngCopy
              Set rngCopy = rngCopy.Offset(1, 0)
          End If
        End If

    Next rw
    If FirstPass Then
        FirstPass = False
        GoTo redo
    End If

End Sub

Use the macro recorder and do a unique advanced filter on the data then you can do your comparisons.
