Shipping cost determination in SD

Hi All,

We have an issue where, the shipment cost is calculated based on the total weight of the materials in Delivery document.( weight involved for packing is not considered)

But the requirement is that the shipment cost should be calculated based on the gross weight of materials, including the weight involved for packing.

Kindly let me know, how to achieve this?

Is there any user exit/Badi for the same?

Rgs,

Priya
