Reversal Of LC amount in case of sales return(shut out process)

[chitranksurana]

I have a case in my organisation where a sales order was created with LC as payment gaurantee, 6 deliveries were created on said sales order but only 4 of them were delivered, now 2 of them are to be returned and sold back at a letter date.

A return order was created taking the invoice of original order as reference. But the LC amount wasnt reversed with it and because of that a new sales order cant be created for remaining 2 delivery's quantity using the same LC

Now my question is, IS the above scenario possible practically or not. If yes how can i get the same configured in my system.

Please Ask if anything needs more info or any misunderstanding.

thankful in advance

Edit: More clarification

In the above case, the logistics dept could only arrange vehicles for 2 of the delivery, so the cust asked for invoice of only those two. Now to return the goods as "not yet sold" (not sure of exact term) a return order is created.All the return entries are being shown in accounting books but the same does not credit into the LC (Financial Doc. Type - Irrevocable Confirmed).

Wondering why you were creating a return order with reference to original sales order when you are suppose to create with reference to billing document.

I'm sorry if im misunderstanding but I did right that under "create with reference" I chose the invoice document of the original sales order.

Also editing the above question with a little more clarification.
