Possible impacts of creating a manual bank statement line while you load and import bank statements?

Summary:

Hi All,

One duplicate journal transaction was entered into cash account by users using spreadsheet. Now, this transaction is causing a difference of 111 CAD in bank balance and the GL account balance, which can be rectified by reversing the duplicate journal. But this reversal activity leads to creation of one unreconciled transaction in Cash management (as the reversal journal is hitting the cash account).

Now, we will not have a actual bank statement line (coming from our bank) to reconcile this extra journal so we are planning to create one manual bank statement line that will reconcile with this journal.
