AR to GL Reconciliation Report
The AR to GL Reconciliation report compares the account balances in Oracle Receivables to those in Oracle General Ledger, and highlights journal sources where discrepancies might exist. This report simplifies the reconciliation process by comparing Receivables and General Ledger account balances in a single place.
Run the AR to GL Reconciliation report:
The AR to GL Reconciliation report prints by ledger and organizes data first by company segment, then account type (assets, liabilities, income, and expense).
This report will show a difference between Receivables and GL account balances only if items did not successfully post to GL accounts. The Difference column indicates that the activity in Receivables compares to the journal source of Receivables in the general ledger. If the actual balance of a specific account is different in Receivables than in the general ledger, then the following columns highlight the type of journals that affect the account balances:
If manual journal entries exist in the general ledger, then you might need to reverse these journal entries if corrections were already made in Receivables.
If other subledgers post to these accounts, then you might need to make corrections in those subledgers, make manual corrections in the general ledger, or reconcile your other feeder systems separately.
After taking the required corrective actions, run the AR to GL Reconciliation report again to confirm that AR and GL accounts are now in balance.
