Sales Refund

Hello Tsolmon ,

The Sales refund can do by following ways:

1)If your sale order 'Shipping policy' is invoice from packing then:
     You can return your packing from stock picking object (Related Menu: Stock Management/Outgoing Products) by calling 'Return packing' wizard. In this wizard you will set your packing into 2 form :
       * First put this into none state but this will make the picking into none state and you can not create any invoice from this created return packing.
      *Second one is 'to be invoiced', from this state you can easily create return invoice by calling 'Create Invoice' wizard.

2)If your sale order 'Shipping Policy' is 'Shipping & Manual Invoice' then:
   In this particular scenario sale order will automatically create a invoice when it is confirmed.
   The related invoice need to be return by calling 'Credit Note' wizard from invoice object.

Rest options are related with above options ,you can choose any one option with respect of their behavior.

Hope this will help you.
Thanks.
