Import Alternative Items

Hi all,

I'm using this code to import alternative items into SAP. It was working with previous versions, but now in SAP 9.1 PL10 it is not working. Any ideas why?

SAPbobsCOM.CompanyService oCompanyService;

                SAPbobsCOM.AlternativeItemsService AltItemsService;

                SAPbobsCOM.OriginalItem OriItem;

                SAPbobsCOM.OriginalItemParams OriItemParams;

                SAPbobsCOM.AlternativeItem AltItem;

                oCompanyService = Globals.oCompany.GetCompanyService();

                error = 2;

                AltItemsService =

                (SAPbobsCOM.AlternativeItemsService)(oCompanyService.GetBusinessService(SAPbobsCOM.ServiceTypes.AlternativeItemsService));

                OriItem =

                (SAPbobsCOM.OriginalItem)(AltItemsService.GetDataInterface(SAPbobsCOM.AlternativeItemsServiceDataInterfaces.aisOriginalItem));

                OriItemParams =

                 (SAPbobsCOM.OriginalItemParams)(AltItemsService.GetDataInterface(SAPbobsCOM.AlternativeItemsServiceDataInterfaces.aisOriginalItemParams));

                //Add 2 Alternative Items to Item A00003

                OriItem.ItemCode = "A02.11028"; // This item has no Alternative Items

                 //Adding first Alternative Item

                OriItem.AlternativeItems.Add();

                AltItem = OriItem.AlternativeItems.Item(0);

                AltItem.AlternativeItemCode = "A02.11028.M01";

                AltItem.MatchFactor = 100;

                //Adding second Alternative Item

                OriItem.AlternativeItems.Add();

                AltItem = OriItem.AlternativeItems.Item(1);

                AltItem.AlternativeItemCode = "A02.11028.M02";

                AltItem.MatchFactor = 100;

                //Adding the new Alternative Items

                OriItemParams = AltItemsService.AddItem(OriItem);
