Cancel request
(copied form user guide)
A Debtor Agent who has initiated a credit transfer can request to cancel this credit transfer. The EPC125-05 SEPA Credit Transfer Scheme Rulebook Version 8.0 lays down the possible reasons for cancelling a credit transfer and establishes that a request for cancellation can be submitted within 10
business days of the execution of a credit transfer. The Debtor Agent, at its own or its client initiative, can submit a request for cancellation for FFPCRQST document transactions, where:
- the credit transfer, by accident, was executed twice (was duplicated); then the ISO code of the reason in the FFPCRQST document transaction must be DUPL;
- was incorrect for technical reasons; then the Proprietary code of the reason in the FFPCRQST document transaction must be TECH;
- was submitted by fraudulence; then the Proprietary code of the reason in the FFPCRQST document transaction must be FRAD.
