Creating A/R invoice draft

Hi all,

I got this working for creating A/P invoice drafts but now I am having difficulty creating a A/ R Invoice draft. I keep getting an error message.

"ClassFactory cannot supply requested class"

Here is my code.

if (vCompany.Connect() == 0)
			SAPbobsCOM.Documents oInvDraft = new SAPbobsCOM.Documents();
			oInvDraft = (SAPbobsCOM.Documents)vCompany.GetBusinessObject(SAPbobsCOM.BoObjectTypes.oDrafts);

			oInvDraft.DocObjectCode = SAPbobsCOM.BoObjectTypes.oInvoices;
			oInvDraft.DocType = BoDocumentTypes.dDocument_Items;
			oInvDraft.CardCode = sSAPCardCode;
			oInvDraft.NumAtCard = sRefNo;
			oInvDraft.HandWritten = SAPbobsCOM.BoYesNoEnum.tNO;
			oInvDraft.PaymentGroupCode = -1;
			oInvDraft.DocDate = DateTime.Now;
			oInvDraft.DocTotal = FormTotal;
oInvDraft.Lines.AccountCode = rReaderLI.GetString(iProdID);
				oInvDraft.Lines.Quantity = 1;
				oInvDraft.Lines.TaxCode = "exempt";
				oInvDraft.Lines.Price = double.Parse(rReaderLI.GetString(iSalePrice));
				oInvDraft.Lines.ItemDescription = rReaderLI.GetString(iProd);
			RetVal = oInvDraft.Add();


Anyone have any ideas?

Thanks, Rhonda

    Hi, Rhonda!

    I suppose the reason is in incorrect adding new lines in a document. The first line doesn't have to be added using "Add" method.

    It's the sample from DI help:


    vInvoice.Lines.ItemCode = "A00023"

    vInvoice.Lines.ItemDescription = "Banana"

    vInvoice.Lines.PriceAfterVAT = 2.36

    vInvoice.Lines.Quantity = 50

    vInvoice.Lines.Currency = "Eur"

    vInvoice.Lines.DiscountPercent = 10

    'Invoice Lines - Set values to the second line


    vInvoice.Lines.ItemCode = " A00033"

    vInvoice.Lines.ItemDescription = "Orange"

    vInvoice.Lines.PriceAfterVAT = 118

    vInvoice.Lines.Quantity = 1

    vInvoice.Lines.Currency = "Eur"

    vInvoice.Lines.DiscountPercent = 10


    Just use the condition to determine whether it is the 1st line or not...

      Well I now am able to add Invoice drafts (thanks for everyone's suggestions) but I have another question that is driving me crazy. (Why is everything so difficult? I almost feel like SAP wants to keep us in the dark.)

      Anyway, the line items include the following:


      Item Detail

      Free Text

      Begin Date

      End Date


      Price after discount



      GL Account

      How the heck do I add Item Detail, Begin Date and End Date? I'm guessing that Item Detail is some sort of lookup based on the item code.

      Some sample code would be most helpful.
