Way Bill

I need answer for the following questions:

1. Give a brief on What is a Way Bill ??? (From what I have researched, I understand that Way Bill is a Shipping document which is given by the consignor to the consignee specifying the details of goods dispatched)

2. A Company dispatches goods to one of its own Sites (another district or another city) where it manufactures a RO Plant. Is the company bound to file WAY BILL ???

3. A Company dispatches goods to the supplier for repairs. Is the company bound to file WAY BILL ???

4. What are the risks/ penalties/ if WAY BILL is not filed by the Company??

Thanks in advance.
