      CpqConstants.DELETE_LINE_ITEM	CpqConstants.ITEM_ID	Method to delete a line item.

2. To work with the the CartItem Wrapper interface:

   1. The line items present in the basket can be accessed using the wrapper class of CpqCartDocumentItem or CpqCartItem. Get the cart wrapper instance for CpqCart or CpqCartDocument using the method:

   2. Call the wrapper APIs using the wrapper.call(methodName, args).

   Sample Code

   • The cart wrapper would internally call the V2 APIs for Digital Commerce or CPQ APIs.
   • The cart wrapper would call the V3 APIs for Standard Digital Commerce APIs.
