Delivery Item in 2LIS_08TRFKZ datasource

Hi,

I want to use the 2LIS_08TRFKZ extractor to load the shipment costs and Qty by Delivery number to BI. I see that I can enhance the extractor to bring the Delivery Number from the VTTP table. But I am wondering how I can get the Delivery Item information and split the Costs and Qty at the Item level.

Please provide some input.

Thanks.
