In the New Bank Reconciliation program, if the opening balance for the first bank statement for the financial year was entered incorrectly, it cannot be changed once bank reconciliations exist for that GL / Bank Account.
Workarounds to resolve this issue:
Note down the discrepancy/variance and carry the variance forward until the start of the new financial year and then enter the correct starting opening balance.
In the New Bank Reconciliation program (General Ledger, Transactions, Bank Reconciliation, Reconcile), delete ALL current bank statement reconciliations and redo them starting with the correct opening balance.
Use the Old Reconcile program for the remainder of the financial year (General Ledger, Transactions, Bank Reconciliation, Old Reconcile). This will allow you to enter the opening balance for each statement from the incorrect date onwards.
Note: If you follow this workaround, you will need to use Old Bank Reconcile for ALL bank reconciliations for the remainder of the financial year, as the new and old bank reconciliation programs use different tables in the Attaché Accounts database.
