I created a pos sale, made payment, posted the journal entries and closed the session. Now i need to perform a reverse entry for that pos order. No need to make reverse the product. Because that sale should be considered as Free of Charge.

In new session,

1. Create a order with negative quantity & amount

2. Make payment 

3. post and close the journals.

Are the above steps will be enough?

or 

 I need to create manual journal entry & post ?

Which solution is best?

Is there any other solution?
