Field help (EPARENPAY) 

A payment reason code is used when generating bank files in SEPA Credit Transfer and SEPA Direct Debit formats.
It corresponds to the 'Remittance information' data from the ISO 20022 standard messages.
This field can be entered provided the payment entry is associated with a payment transaction accepting SEPA format. It can be used to enter a reason for each payment (maximum length = 140 characters).
