Re: Change Payment Method in AR Invoice

You may try this also.

            Dim Inv As SAPbobsCOM.Documents

            Inv = oCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oInvoices)

            With Inv

                If .GetByKey("1") Then

                    Inv.PaymentMethod = "30D"

                    If Not .Update = 0 Then

                        MsgBox(oCompany.GetLastErrorDescription)

                    End If

                End If

            End With

You can't update paid invoice or closed.
