MT 578 Network Validated Rules

C1 

The following amount fields cannot appear in more than one occurrence of subsequence E3 Amounts (Error code(s): E87):

Subsequence E3
:19A::ACRU
:19A::CHAR
:19A::DEAL
:19A::EXEC
:19A::LOCL
:19A::LOCO
:19A::OTHR
:19A::SETT
:19A::STAM
:19A::TRAX
:19A::WITH
:19A::COAX

C2 

If the alleged instruction is against payment (:22H::PAYM//APMT in sequence B) then it is mandatory to specify a settlement amount: one occurrence of subsequence E3 Amounts must contain amount field :19A::SETT (Error code(s): E83).

Sequence B
if field :22H::PAYM is ...
Then subsequence E3 is ... And in one occurrence of subsequence E3 :19A::SETT is ...
APMT Mandatory Mandatory
Not equal to APMT Optional Optional

C3 

If an Exchange Rate (field :92B::EXCH) is present, the corresponding Resulting Amount (field :19A::RESU) must be present in the same subsequence. If the exchange rate is not present then the resulting amount is not allowed. This check applies within each occurrence of subsequence E3 (Error code(s): E62).

Subsequence E3
if field :92B::EXCH is ...
Subsequence E3
then field :19A::RESU is ...
Present Mandatory
Not present Not allowed

C4 

The following party fields cannot appear more than once in a message (Error code(s): E84):

Subsequence E1 Subsequence E2
:95a::BUYR :95a::ACCW
:95a::DEAG :95a::BENM
:95a::DECU :95a::PAYE
:95a::DEI1 :95a::DEBT
:95a::DEI2 :95a::INTM
:95a::PSET  
:95a::REAG  
:95a::RECU  
:95a::REI1  
:95a::REI2  
:95a::SELL  

C5 

If the alleged instruction is a Delivery (:22H::REDE//DELI in sequence B) then it is mandatory to specify a delivering agent: one occurrence of subsequence E1 Settlement Parties must contain party field :95a::DEAG (Error code(s): E85).

If the alleged instruction is a Receipt (:22H::REDE//RECE in sequence B) then it is mandatory to specify a receiving agent: one occurrence of subsequence E1 Settlement Parties must contain party field :95a::REAG (Error code(s): E85).

Sequence B
if field :22H::REDE is ...
Then in one occurrence of subsequence E1 field :95a::DEAG is ...
DELI Mandatory

Sequence B
if field :22H::REDE is ...
Then in one occurrence of subsequence E1 field :95a::REAG is ...
RECE Mandatory

C6 

If a qualifier from the list Deliverers is present in a subsequence E1, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Deliverers (see below) must be present (Error code(s): E86).

In other words, in sequence E, the following scenarios must be validated:

If a qualifier from the list Receivers is present in a subsequence E1, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Receivers (see below) must be present.

In other words, in sequence E, the following scenarios must be validated:

Deliverers   Receivers  
DEI2 Deliverer's Intermediary 2 REI2 Receiver's Intermediary 2
DEI1 Deliverer's Intermediary 1 REI1 Receiver's Intermediary 1
DECU Deliverer's Custodian RECU Receiver's Custodian
SELL Seller (Deliverer) BUYR Buyer (Receiver)

C7 

If the message is a cancellation or a removal, that is, Function of the Message (field 23G) is CANC or REMO, then subsequence A1 (Linkages) must be present at least once in the message, and in one and only one occurrence of A1, field :20C::PREV must be present; consequently, in all other occurrences of A1, field :20C::PREV is not allowed (Error code(s): E08).

Sequence A
if field :23G: is ...
Then subsequence A1 is ... And field :20C::PREV is ...
CANC or REMO Mandatory (minimum one occurrence of A1 must be present) Mandatory in one occurrence of subsequence A1, and not allowed in all other occurrences of subsequence A1
NEWM Optional Not applicable

C8 

In subsequence E1, if field :95a::PSET is present, then field :97a::SAFE is not allowed in the same subsequence (Error code(s): E52).

Subsequence E1
if field :95a::PSET is ...
Subsequence E1
then field :97a::SAFE is ...
Present Not allowed within the same occurrence
Not present Optional

C9 

A value date must only be provided for cash/securities split settlement. That is, in any occurrence of subsequence E3, if value date field :98a::VALU is present, then in sequence E field :22F::STCO//SPST must be present, and settlement amount field :19A::SETT must be present in the same subsequence E3 (Error code(s): C28).

In any occurrence of
subsequence E3
if field :98a::VALU is ...
Sequence E
then field :22F::STCO//SPST with DSS not present is ...
In the same occurrence of
subsequence E3
and field :19A::SETT is ...
Present Mandatory Mandatory
Not present Optional Optional
