The payment lot processing is explained in lesson 4 of this unit.
The payment lot processing clears most of the open items automatically via the flexible and configurable clearing control.
The payment lot processing creates clarification cases for all payments that can't be assigned to an open item. They are placed in the clarification list to be reviewed manually and item by item with the SAP Fiori App Clarify Incoming Payments (see next figure).
Furthermore, the amounts of all payments that can't be assigned to an open item, are posted to a clarification account.

The SAP Fiori App Clarify Incoming Payments provides the following clarification possibilities:
- You can correct the data to identify the item to be cleared and restart the posting.
- You can clear manually. Partial clearings can be posted more than once. It is also possible to transfer posting items by using a short account assignment. In connection with this a workflow sends an e-mail to the department receiving the posting.
- You can post the payment from the clarification account to the contract account, if the contract account can be found, but not the open item. This is called "posting on account".
- You can post the payment from the clarification account to an interim account (from where it could be selected later for a repayment run), if the contract account cannot be found.
- You can create a repayment request if you could not assign the payment at the end. In this case, the amount is posted from the clarification account or interim account to a repayment clearing account.
