BAPI Access from Excel using VBA

Question

Im writing an excel macro (VBA) to call a bapi that populates a spreadsheet.
The user will then do some manipulation of the data collected, and then it must be sent back to sap.
The Bapi in question is BAPI_GET_USER_DETAIL
*"  IMPORTING
*"     VALUE(USERNAME) LIKE  BAPIBNAME-BAPIBNAME
*"  EXPORTING
*"     VALUE(LOGONDATA) LIKE  BAPILOGOND STRUCTURE  BAPILOGOND

*"     VALUE(SNC) LIKE  BAPISNCU STRUCTURE  BAPISNCU

Ive Managed to glean from various sources on the internet, the various basics on doing a bapi call from VBA
Here is what i have so far.
Private Sub Fetch_User_details_Click()
'Take username in cell 2,2 and check to see it it exists.
'Display the First and Last name of the user
'Get list of all roles and their expiry dates and populate list
Dim R3, MyFunc, App As Object
Dim SEL_TAB, NAMETAB, TABENTRY, ROW As Object
Dim Result As Boolean
Dim iRow, iColumn, iStart, iStartRow As Integer
'RFC Paramaters
Dim Pusername As Variant
Dim Preturn As Variant
Dim copyFromc As String
'Clear Table Section of Spreadsheet
Worksheets("Sheet1").Select
For x = 9 To 200
  For y = 1 To 8
    Worksheets("Sheet1").Cells(x, y).ClearContents
    Next y
Next x
'Create Server object and Setup the connection
Set R3 = CreateObject("SAP.Functions")
R3.Connection.System = ""
R3.Connection.client = ""
R3.Connection.user = ""
R3.Connection.Password = ""
R3.Connection.Language = "EN"
'Logon to SAP
If R3.Connection.logon(0, False) <> True Then
   Exit Sub
End If
'R3.loglevel = 9
'R3.logfilename = "c:guilog.txt"
Set MyFunc = R3.Add("BAPI_USER_GET_DETAIL")
copyFromc = Worksheets("Sheet1").Cells(3, 2).Text
Set Pusername = MyFunc.exports("USERNAME")
Pusername.Value = copyFromc
'Call the BAPI
If MyFunc.call Then
'  ok now what ?
' Process the returned data into the spreadsheet
Else
    MsgBox ("Call returned FALSE")
End If
'Close Connection to SAP
R3.Connection.logoff
End Sub
To update the data ( User Role Assignements ) i will be using bapi BAPI_USER_ACTGROUPS_ASSIGN
*"*"Lokale Schnittstelle:
*"  IMPORTING
*"     VALUE(USERNAME) LIKE  BAPIBNAME-BAPIBNAME
*"  TABLES
*"      ACTIVITYGROUPS STRUCTURE  BAPIAGR
*"      RETURN STRUCTURE  BAPIRET2
* Dieser Baustein ist gleichgestellt mit der Pflege eines Benutzers
* über die Pflegetransaktion, gepflegt werden die Felder, für die die
* Pflege erlaubt ist
I need help deciphering the data received from the bapi and then repackaging it using VBA.
I know writing this in ABAP would take less than 30 mins, but that is not an option for me.

Answer 1

Ok, Ive made some headway
I can now Read all the data i need from SAP
Now comes the bit to write it back again.  Will Update when i have a solution
Private Sub copydata_Click()
Dim x1 As Integer, x2 As Integer
'copy all data from "Copy From" to "Copy To"
'first determine how many rows contain roles
'before copying the roles, check that the destination user has no roles assigned
If Cells(9, 6).Text <> "" Then
   MsgBox ("Error. Destination User already has Roles assigned.")
   Exit Sub
End If
For x1 = 0 To 1000
   If Cells(9 + x1, 1).Text = "" Then
     Exit For
   End If
Next
Worksheets("Sheet1").Range(Cells(9, 1), Cells(9 + x1 - 1, 4)).Copy _
   Destination:=Worksheets("Sheet1").Range(Cells(9, 6), Cells(9 + x1, 9))
For x2 = 1 To x1
Worksheets("Sheet1").Cells(9 + x2 - 1, 8).Value = Date
Next
End Sub
