Bank Reconciled transactions are shown as not reconciled

Hello,

After upgrade from 8.82 PL 13 version to 9.0 PL 11 version all Bank Reconciled transactions are opened and in Bank Reconciliation Report I got message "This Reconciliation has been cancelled" . How can I retrieve it. I have gone through two SAP Note 903688 and 936485 but I can't understand the solution, please help me. 😔

Thanks
