MT196: Answers (Customer Messages)

This message is sent by a financial institution to provide answers, confirmations, or status information in response to queries or requests related to customer messages. MT196 is used for answering customer credit transfer queries and other customer-related inquiries.

Key Features

• Answer provision: Official responses to customer message queries
• Reference tracking: Links to the original message through reference fields
• Conditional structure: Either narrative (field 79) or copy of original message fields
• Answer codes: Standardized answer codes with supplementary data
• Narrative support: Additional narrative description capability

Field Structure

The message follows a conditional structure where either field 79 (narrative description) or a copy of the mandatory fields from the original message may be present, but not both.

Answer Process

Used when a receiver needs to provide answers, confirmations, or status updates regarding previously received customer messages, including confirmations of execution, status updates, or responses to specific queries.

Fields

field_20: GenericReferenceField

Transaction Reference Number - Field 20

Unique reference assigned by the sender for this answer message. This reference is used throughout the answer lifecycle for tracking, acknowledgment, and audit purposes. Must be unique within sender’s system per business day.

field_21: GenericReferenceField

Related Reference - Field 21

Contains the reference from field 20 of the message being answered. This creates a direct link between the answer and the original message, enabling complete audit trails and transaction tracking.

field_76: GenericMultiLine6x35

Answers - Field 76

Contains response codes, narratives, and supplementary data. Includes confirmation codes (1-33), cancellation codes (CNCL, PDCR, RJCR), and reason codes with optional supplementary details in parentheses.

field_77a: Option<GenericMultiLine20x35>

Narrative - Field 77A (Optional)

Free-form narrative description that supplements the answer codes in field 76. Used for providing additional context, explanations, or details about the answers.

field_11a: Option<GenericTextField>

MT and Date of the Original Message - Field 11a (Optional)

Specifies the message type and date of the original message being answered. Can be in Option R format (with session/ISN) or Option S format (date only).

field_79: Option<GenericMultiLine6x35>

Narrative Description of Original Message - Field 79 (Conditional)

Contains narrative description of the original message being answered. Must be present if copy of original message fields is not included. Cannot be used together with copy of original message fields.

field_23b: Option<GenericTextField>

Copy of Mandatory Fields from Original Message - Multiple Fields (Conditional)

field_32a: Option<Field32A>

field_50: Option<Field50>

field_59: Option<Field59>

field_71a: Option<GenericTextField>
