Direct debit authorization amendment resulting in bank failing collections

Hi all,

Our client make amendments to 2 of their customer mandates.

For both mandates, I can see a new version of the same mandate record in IBY_DEBIT_AUTHORIZATIONS (a new debit_authorization_ID having the same authorization_reference_number and point to initial _debit_authorization_id).

For customer A there was no reason entered for the amendment and I can see from the documentation that this is a required field.

However the system allowed the user to update the mandate without this field and created a version 2 of the mandate.

The rejection code from the bank for this collection was "MANDATE DATA MISSING OR INCORRECT"
