Methods to change a financial record that is in a financial lockdown period
Financial lockdown helps to make sure that your organization has accurate financial records. Thus, you usually cannot directly make changes to a financial record that is in a financial lockdown period. But you can use alternative methods to make record changes (for example, to make corrections to invoices and payments that are not accurate).
For an invoice that is in a financial lockdown period, you can make a credit note that removes the value of the initial incorrect invoice. Then, make an invoice that has the correct information.
For a payment that is in a lockdown period, you can do a refund that removes the value of the initial incorrect payment. Then, make a payment that has the correct value.
