Hi Samant,
You have to write Item Cost for the items for which there is no cost record in SAP. So therefore while posting stand alone AR Sale Return document, you should have written the item cost for the respective items. Due to unavailability of the item cost, SAP entered these items with zero cost and thus posted no JE for this transaction.
For correction you have to go to Inventory--->Inventory Transactions--->Inventory Revaluation. Here select Revaluation Type as "Price Change" and then select the item(s) along with its respective warehouse and quantity. In below area write down new price (item cost) for the items and post it. The Stock accounts of the respective items would be debited and the G/L increase account would be credited in the transaction. After posting this the cost of affected items would be correct now.
Hope this would help you in solving the problem.
Regards,
Azeem
