MT 365 Network Validated Rules

C1 

The message must contain the current fixed interest rate(s). The use of the fixed interest rate sequences depends on the type of the original transaction. Thus, the presence of sequences B and E depends on subfield 1 of field 23A of sequence A as follows (Error code(s): E33):

Sequence A if subfield 1 of field 23A is ...	Then sequence B is ...	And sequence E is ...

C2 

The new fixed rates should only be used in the case of recouponing; the new notional amounts should only be used in the case of a partial termination. Thus, in sequence A, the presence of fields 32G, 33E and 22D and, in sequences B and E, the presence of field 37P, depends on field 22B in sequence A as follows (Error code(s): E34):

Sequence A if field 22B is ...	Sequence A then field 32G is ...	Sequence A and field 33E is ...	Sequence A and field 22D is ...	Sequence B and field 37P is ...	Sequence E and field 37P is ...

C3 

The second intermediary field can only be used if more than one intermediary is required. Thus, for all occurrences of fields 56a and 86a, the following rules apply (Error code(s): E35):

In any sequence, if field 56a is ...	Then, in the same sequence, field 86a is ...
Present	Optional
Not present	Not allowed

C4 

The related reference is required in the case of an amendment or cancellation. Thus, in sequence A, the presence of field 21 depends on field 22A as follows (Error code(s): D02):

Sequence A if field 22A is ...	Sequence A then field 21 is ...
AMND	Mandatory
CANC	Mandatory
DUPL	Optional
NEWT	Optional

C5 

In sequence A, if field 22D contains code OTHR, then field 37N must be present (Error code(s): E36).

C6 

In all optional sequences, the fields with status M must be present of the sequence is present, and are otherwise not allowed (Error code(s): C32).
