Version conflict? Error -5002 when adding a sales order in SDK 2004.

Question

I get the -5002 error without any description when I reference the "SAP Business One Objects Bridge API version 6.2 SP3" and try to add an invoice in SBO 2004. The code is basically:
Set vDOC = vCmp.GetBusinessObject(oInvoices)
vDOC.CardCode = "K99999"
vDOC.CardName = "Nils"
vDOC.Lines.ItemCode = "A00001"
VDOC.Add
The routine works well if I reference the SBO 2004 DI API or if I run it on a 6.5 system.
How can I be sure that my routine can work in both versions?

Answer 1

I run Windows XP Proffessional with SP2.
1) I had 6.5 SP1 installed. My POS-app works well. I have a procedure that adds an invoice from the POS-app. The VB-project (VB6 SP5) references "SAP Business One Objects Bridge API version 6.2 SP3" (because I want to support all versions of SBO).
2) I uninstall SBO 6.5 and install SBO 2004 (III).
3) I start the POS-app and receives an error when I try to add a document. The message is "-5002,". No text after the errorcode.
4) I then deletes the reference to "SAP Business One Objects Bridge API version 6.2 SP3" and reference the "SAP Business One DI API Version 2004".
5) I then start the POS-app again and no error occurs.
The code I debuged with is as simple as this:
    Set vDOC = vCmp.GetBusinessObject(oInvoices)
    Set vOCRD = vCmp.GetBusinessObject(oBusinessPartners)
    vDOC.CardCode = "K99999"
    vDOC.CardName = "Nils"
    vDOC.Add
    vDOC.Lines.ItemCode = "A00001"
    vDOC.Lines.ProjectCode = "    "
    vDOC.Lines.ItemDescription = "Varetekst"
    vDOC.Lines.Quantity = 1
    vDOC.Lines.PriceAfterVAT = 100
    vDOC.Lines.DiscountPercent = 0
    If (0 <> vDOC.Add()) Then
       Call vDOC.SaveXML("SAP_ERR_" & Trim(Str(DocType)) & "_" & Trim(Str(Bong)) + ".xml")
       isCancelled = True
    End if
    Exit Function
Strange?
