The document describes the functionality for automatic clearing in SAP, which allows clearing of multiple GL accounts in one transaction. It can be used to automatically clear debits and credits for accounts managed on an open item basis, such as accrual accounts, at the end of each month. The GL accounts must be flagged as open item, and up to three customizing fields can be defined as sort criteria to determine which documents can be cleared together, such as by assignment number. The steps provided show how to run an automatic clearing without specifying a clearing currency by selecting the company code, fiscal year, GL account, and executing the transaction in test mode first before actual posting.
