Latest SAP SD Interview Questions and Answers 
Question 1: Sales BOM and Delivery Group
We create an order for a sales BOM with three sub items.
  Since the sub item components must not be delivered
  without the main product we declared the main item
  category as delivery group. The problem arises when
  there is zero availability for the main item and no
  schedule line can be confirmed. The main item is
  defined as delivery group but the delivery is created
  without the main and only the component sub items.
  The delivery group becomes broken up. This occurs
  only in VL01N and VL10 dialogue mode. In VL10
  background it works ok, so no delivery item is created at
  all for those unconfirmed items. How do we fix this?
  
A: The message is not configurable; at least in releases <= 4.6. But you can change the 'W' to an 'E' with a modification.
Question 2: Stock Transfer

Question 2: Stock Transfer
How do we transfer stocks under one company code
  from plant to plant?
  
A: Plant to plant is handled using MB1B. If stock transfer orders with deliveries are configured, use ME27.
