generally, these three functions are needed to modify last month's voucher. Because the normal process is approval, bookkeeping and bookkeeping, you have to do it in reverse to modify the approved bookkeeping and closing work. Cancel closing: refers to returning to the state before closing last month. Select the month (usually last month) to be closed in the closing interface and use the shortcut key SHIFT+CTRL+F6 to return to the state before closing last month. Anti-bookkeeping: it means to restore the pre-bookkeeping status. In the reconciliation interface, use the shortcut key CTRL+H to activate the "Restore Pre-bookkeeping Status" function, and then a button for restoring bookkeeping will appear below the bookkeeping function. Just click Use. De-approval: it means that the approved voucher is unapproved. Just click the corresponding voucher in the approval voucher interface as the approver and cancel the approval.

it's very tiring to play by hand, please understand.
