In the GnuCash register there is a column named R.
This field indicates the status of a transaction. Possible values are:
Default status when a transaction is created
Cleared. Status may be assigned either manually or by an import process.
Status assigned solely by the reconciliation process (see Sezione 5.8, «Riconciliare un conto a un estratto conto»). Places limits optionally requiring confirmation on editing fields in that line of a transaction.
Frozen. Not implemented at this time
Voided. Status is assigned or released manually through the transaction menu (Sezione 4.3.2.4, «Registro del conto - Menu ») to a transaction and applies to every line in the transaction. It hides most of the transaction details but does not delete them. When a transaction is voided a reason entry is required that appears to the right of the description.
