What acmt.016 is for

The AccountExcludedMandateMaintenanceAmendmentRequest message is sent from an organisation to a financial institution as part of the account maintenance process. It is sent in response to a request from the financial institution to send additional information. Usage: this update is about account details excluding any mandate information.
If modification codes are not used: the organisation will specify under the “Account” and “Organisation” tags the complete information as it should be in the financial institution’s records after processing the update request.
If modification codes are used (in that case, they must be used everywhere): the organisation will specify under the “Account” and “Organisation” tags which elements must be added, deleted, modified, or if they are unchanged.
