The general steps in returns lot processing are as follows:
Create the Returns Lot
The returns lot can be created manually or by a program (bank statement file upload).
Change the Returns Lot
Items can be inserted or deleted, corrections to items are permitted.
Close the Returns Lot
Items can no longer be inserted or deleted; however, corrections to items are permitted.
Post the Returns Lot
The returns lot can only be posted after it has been closed. Post processing is required if the returns could not be posted.

If the Amount Includes Charges indicator is set, all return amounts belonging to this return lot are evaluated by the system as gross amounts. The net amount is calculated as follows: net amount = returns amount - charge amount. If the indicator is not set, the return amounts are evaluated as net amounts (net amount = return amount).
If the Charge Includes Tax indicator is set, all charges relating to this returns lot (bank charges, charges passed on) are evaluated by the system as gross charges. The net charge is calculated as follows: net charge = Charge amount - tax amount or net charge = charge amount.
If the Enhanced Return Processing indicator is set, you can post returns to payments that contained down payments or postings on an account where these items had been cleared again.
The selection categories available here are the same ones that are available when posting a payment lot. Delivered selection categories relevant for returns processing include document and check number.
You can use event 255 to define your own selection categories.
Within configuration, defaults can be set for document type, clearing reason, company code, screen variant, and selection category that will be used when posting a return lot.
If you do not enter a bank clearing account number in the returns lot item, the system will automatically use the bank clearing account defined in customizing for the given return type (bank return, check return) when the return lot is posted. If you do not know the actual bank clearing account number, but you do know the house bank and account ID, you can enter both and the system will determine the appropriate clearing account.
