E-way bill- what is line sales or recipient not known.?

Can you tell me what is line sales?

Taking goods from main business permisses to some where out of home town. And showing good to clients (number of) they will take what they want. So can come to know how much value sold to a client and who is client only after movement of goods. (The destination also unknown). This is they call as line sales

While generating an E-Way Bill, you have to opt for ''Recipient not known'' sub-type when Goods are being moved to another place but the actual buyers of the goods are not known at the time of start of movement. For eg- If any person has to move his goods to a marketplace where he'll find many customers, he'll select the "recipient not known" sub-type.

The "Line sales' sub-type is very similiar to the above mentioned subtype. "Line sales" is generally used for door to door selling of goods.

However more clarification is required from the GST Council regarding the correct situations for usage of both these subtypes.
