MT101 Transaction (Sequence B)

Purpose

Represents a single transaction within an MT101 message. Each occurrence provides details for one individual funds transfer request.

Field Details

• 21: Transaction Reference (mandatory) - Unique reference for this transaction
• 21F: F/X Deal Reference - Required when field 36 is present (NVR C1)
• 23E: Instruction Code - Special instructions (e.g., EQUI for equivalent transfers)
• 32B: Currency/Transaction Amount - The amount to be transferred
• 33B: Currency/Original Amount - Used for currency conversions (NVR C2, C5)
• 36: Exchange Rate - Required when 33B present and amount ≠ 0 (NVR C2)

Party Chain

The transaction flow follows: Instructing Party → Ordering Customer → Account Servicing Institution → Intermediary → Account With Institution → Beneficiary

Validation Notes

• If 36 present, 21F must be present (C1)
• If 33B present and 32B amount ≠ 0, then 36 mandatory (C2)
• Currency in 33B must differ from 32B (C5)
• If 56a present, 57a must be present (C7)

Trait Implementations

impl Clone for MT101Transaction

fn clone(&self) -> MT101Transaction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MT101Transaction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MT101Transaction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl PartialEq for MT101Transaction

fn eq(&self, other: &MT101Transaction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
