Compare 2 cells in excel using VBA for SAP GUI scripting

Question

Currently I have a script to copy data from an excel sheet and paste it in SAP in the transaction code scal.

What my code does, is filter the calendar selection by each ID (eg AA/AB) and then copy the data for Start Date and End Date into the scal ID. Save the changes and then move onto the next ID.

Let's say I have an excel sheet with more than one entry for the same calendar ID. What can I do to make excel check if the next row has the same calendar ID as the current one, and then, instead of saving, copy and paste the start/end date for the same ID and only then moving onto the next one.

tldr:compare current column and the column below; if both columns are same, continue with the changes; otherwise save and go back.

Code is given below:

Sub Main()
    Dim row As Integer
    Dim Session

'1. System name entry
    sSystemName = sSystemName_EntrySTD()
'2. Connect to open SAP session
    If bSessionConfirmSTD(Session, sSystemName) = False Then
        MsgBox sSystemName & " session is not opened", vbCritical
        End
    End If

'3. Display status in EXCEL
    application.StatusBar = "Attached to active session"

    On Error Resume Next

'4. for all rows in active sheet (Tabelle1)
    row = 2
    While Tabelle1.Cells(row, 1).Value <> ""

        Dim s1, s2, s3, s4, s5, s6, s7, s8, s9, s10, s11, s12, s13, s14, s15, s16, s17, s18, s19 As String
        Dim i As Integer

'5. Get value from first column of current row
        s1 = Tabelle1.Cells(row, 1).Value
        s2 = Tabelle1.Cells(row, 2).Value
        s3 = Tabelle1.Cells(row, 3).Value
        s4 = Tabelle1.Cells(row, 4).Value
        s5 = Tabelle1.Cells(row, 5).Value
        s6 = Tabelle1.Cells(row, 6).Value
        s7 = Tabelle1.Cells(row, 7).Value
        s8 = Tabelle1.Cells(row, 8).Value
        s9 = Tabelle1.Cells(row, 9).Value
        s10 = Tabelle1.Cells(row, 10).Value
        s11 = Tabelle1.Cells(row, 11).Value
        s12 = Tabelle1.Cells(row, 12).Value
        s13 = Tabelle1.Cells(row, 13).Value
        s14 = Tabelle1.Cells(row, 14).Value
        s15 = Tabelle1.Cells(row, 15).Value
        s16 = Tabelle1.Cells(row, 16).Value
        s17 = Tabelle1.Cells(row, 17).Value
        s18 = Tabelle1.Cells(row, 18).Value
        s19 = Tabelle1.Cells(row, 19).Value

Answer 1

No idea if I understood it correctly, what should be compared actually. But one possible solution might look like this:

. . .
'4. for all rows in active sheet (Tabelle1)
row = 2
While Tabelle1.Cells(row, 1).Value <> ""

    Dim s1, s2, s3, s4, s5, s6, s7, s8, s9, s10, s11, s12, s13, s14, s15, s16, s17, s18, s19 As String
    Dim i As Integer

'5. Get value from first column of current row
    s1 = Tabelle1.Cells(row, 1).Value
    if Tabelle1.Cells(row + 1, 1).Value <> "" then
       if s1 = Tabelle1.Cells(row + 1, 1).Value then row = row + 1
    end if
    s2 = Tabelle1.Cells(row, 2).Value
    . . .
