Hello,

I have a excel sheet that have 3 buttons one to connect to a sap system, one to connect with a function in a sap system and download a table from there and show in the excel sheet, and one that i want to connect to another function and upload the data in the sheet and send it to the function. The download is working well but the upload don't work. here is the code.

' Declaration for the necessary objects
Dim objBAPIControl, objConnection As Object
Dim objTeste As SAPFunctionsOCX.Function
Dim objTable As SAPTableFactoryCtrl.Table
Dim login As Boolean

Private Sub DOWNLOAD_Click()
On Error Resume Next
' The required BAPI
Set objTable = Nothing
Set objTeste = objBAPIControl.Add("ZPD_TESTE_EXCEL")
If objTeste.Call Then
Set objTable = objTeste.Tables("T_INTER")
For i = 1 To objTable.RowCount
ActiveSheet.Cells(8 + i, 1) = objTable.Cell(i, 1)
ActiveSheet.Cells(8 + i, 2) = objTable.Cell(i, 2)
ActiveSheet.Cells(8 + i, 3) = objTable.Cell(i, 3)

Next i
Else
MsgBox "Erro a chamar a função."
End If
' objTable.AppendGridData
End Sub

Private Sub LOGON_Click()
If login = False Then
