Why won't my reconciliation statement end date save?

When trying to complete a bank reconciliation, a statement beginning, ending, and date are all required fields. After a period has been closed, the statement end date will automatically adjust to the end of the next month. 

If unable to type or select the date when setting the date field, this is most likely being caused because that reconciliation period has already been closed. To reopen a closed reconciliation period, view How to reopen a closed reconciliation period.
