# Mark Pennylane bank transactions as having a lost receipt

Automatically mark Pennylane bank transactions as having a lost receipt on app.pennylane.com. Marks one or more Pennylane bank transactions as having a lost receipt, as the transaction's Proof menu does, so they stop showing as waiting for a receipt. With dryRun (default true) each transaction is opened and its Proof menu used, but the change is held back. With dryRun false it is saved, then read back. Returns, per transaction, its label, amount, whether it is still pending at the bank, whether a receipt was already lost or attached before the run, and whether it is now marked lost. A transaction that already has a receipt attached is left as it is, with a warning. Fails when a transaction id does not exist and when signed out of Pennylane.
