Can I delete a reconciled expense transaction, create a replacement transfer transaction, and mark the transfer as Reconciled?

Good day, drew-joosten-rev. 

Editing reconciled transactions may result in discrepancies between your previous and next reconciliation balances. Before making any changes, I recommend contacting an accountant to help you manage the reconciled transaction so it doesn't mess up your books. 

If you need to make changes to the transaction, follow these steps:

1. Go to Accounting.
2. Click on Chart of Accounts tab.
3. Choose the bank account, then hit View register.
4. Look for the transactions and check if you can see R in the column.
5. Select the transaction and repeatedly click the R status until it's blank or unreconciled.
6. Click Edit. Make the changes and then save.
