Upload CSV File to ISA basket

Hello,

I want to upload an CSV File into the ISA shopping card.

I have developed following steps for that:

BusinessObjectManager bom =

(BusinessObjectManager) itemSalesDoc.getBOM(

BusinessObjectManager.ISACORE_BOM);

Basket basket = bom.getBasket();

itemData = basket.createItem();

itemData.setProduct("P-4712");

...

itemList.add(itemData);

itemSalesDoc.setAttribute(MaintainBasketBaseAction.RK_ITEMS, itemList);

Aftr that the forward goes to the "addToBasket.do".

But ist didn´t works. I always get an error message.

Can anybody help me?

Kind regard Axel
