What it means in practice

In a camt.056 cancellation request (or camt.055 from a customer), a cancellation reason code explains why the sender asks for a payment to be stopped or its funds returned. It sits in Undrlyg/TxInf/CxlRsnInf/Rsn/Cd.

The amount received is not the amount that was agreed or expected. In cancellation requests it asks to stop a payment sent with the wrong amount.

What to do

Agree the correct amount with the counterparty, cancel or return the wrong payment, then send a new one.
