Reconciliation Guidance for Missing Statement

Reconciling missing transactions from the previous month will create ending and beginning balance discrepancy, @Som123. 
 

The correct way to do this is to wait until you receive the missing statement. Once you have it, manually enter the transactions associated with that period. You can undo the entire reconciliation and perform a mini reconciliation. 

You can refer to this guide: Reconcile previously deleted and re-entered checking or credit card transactions.

I would also recommend consulting your accountant for additional guidance before proceeding with this.

In case you want to run your previous reconciliation reports to fix the current discrepancies, you can check this guide: Get reports for previous reconciliations in QuickBooks Desktop.

Once you reconcile a month, you cannot undo the reconciliation without affecting subsequently reconciled months.  However, you can reconcile the missing month and put the month-end discrepancy (assuming there is one) into a Reconciliation Discrepancies expense account.  Then, when you get the statement, you can reclassify the amount in Reconciliation Discrepancies to the appropriate P&L/balance sheet accounts with journal entries.  That could be a tedious process if a large number of transactions hit the bank account in a month,
