In Billing Document created with reference to a Delivery in which batch split happens, one material has correct quantity and the other same material's quantity is zero.

Open a billing document in app Change Billing Document or Manage Billing Document, two item lines with same material exist.

But for the 1st item line, there is a quantity; for the other the quantity is zero.

Correct system behavior. 

The billing document will bill the batch main item and only display the batch subitem.
