Special Prices DI Object in 2005 SP1 PL4

Question

Hi all, I've been trying to use DI Object's Special Prices to add a new record. I'm using SAP B1 2005 SP01 PL4. I've heard that this Special Price bug revolving Invalid Date Range was fixed in this patch, but I've tried many times to no avail.
Here is my code:
    Private Sub InsertSpecialPrices()
        Try
            Dim oSpecialPrices As SpecialPrices = oCompany.GetBusinessObject(BoObjectTypes.oSpecialPrices)
            ' SpecialPrices settings
            oSpecialPrices.ItemCode = "A1000"
            oSpecialPrices.CardCode = "C1000"
            oSpecialPrices.AutoUpdate = BoYesNoEnum.tYES
            oSpecialPrices.PriceListNum = 3
            oSpecialPrices.DiscountPercent = 50
START -
            ' SpecialPricesDataAreas settings
            oSpecialPrices.SpecialPricesDataAreas.SetCurrentLine(0)
            oSpecialPrices.SpecialPricesDataAreas.DateFrom = "2006-06-13"
            oSpecialPrices.SpecialPricesDataAreas.Dateto = "2006-06-20"
            oSpecialPrices.SpecialPricesDataAreas.AutoUpdate = BoYesNoEnum.tYES
            oSpecialPrices.SpecialPricesDataAreas.Discount = 15
            oSpecialPrices.SpecialPricesDataAreas.PriceListNo = oSpecialPrices.PriceListNum
            oSpecialPrices.SpecialPricesDataAreas.PriceCurrency = "GBP"
            oSpecialPrices.SpecialPricesDataAreas.Add()
END -
            oSpecialPrices.Add()
            oCompany.GetLastError(lErrCode, sErrMsg)
            If lErrCode <> 0 Then
                MsgBox(lErrCode & ": " & sErrMsg)
            End If
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub
I always get the message "Invalid Date Range", unless I comment out the region between START and END as shown above.
I've even tried other forms of dates like "new Date(2006, 06, 15)", "20060516", "2006-05-16", etc. Can someone tell me if there is anything wrong?
Thanks for assisting,

Answer 1

Hi Jose,
Yes this error is from SAP, specifically from the oCompany.GetLastError method.
I've tried all sorts of Date format, and using both String and Date type, and in all cases I still get the Invalid Date Range error.
I'm pretty sure this is not about the date input format, because incorrect date format would have thrown me an exception on SQL's expression error. This error is more likely that SAP treats my input to be of incorrect RANGE.
I've made sure that my DateFrom is definitely earlier than my DateTo field. So now I'm at a total lost about what to do.
Perhaps I should ditch the Special Prices object and directly manipulate the data from OSPP and SPP1?
