System Matching, also called Automated Transaction Matching, uses a high-speed matching engine to pair a bank record with a general ledger record.
Following System Matching, you will do Manually Matching to pair bank records that required multiple general ledger records to create a match.
From the Bank Reconciliation Main Home tab, click the Matching Window button.
If you watch quickly, you will see the progress of the Automated Transaction Matching.
After System Matching, you will perform Manual Matching.
