MT 518 Network Validated Rules

C1 

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, the Resulting Amount is not allowed (Error code(s): E62).

Subsequence C3
if field :92B::EXCH is ...
Subsequence C3
then field :19A::RESU is ...
Present Mandatory
Not present Not allowed

C2 

If the Settlement Amount (:19A::SETT) is present in sequence B, it must not be present in any occurrence of subsequence C3 (Error code(s): E73).

Sequence B
if field :19A::SETT is ...
Then, for each occurrence of subsequence C3
field :19A::SETT is ...
Present Not allowed
Not present Optional

C3 

If the message is a cancellation, that is, Function of the Message (field 23G) is CANC, 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 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

C4 

The following party fields for subsequences C1 and C2 cannot appear more than once in sequence C. The party fields for sequence D cannot appear more than once in a message (Error code(s): E84).

Subsequence C1 Subsequence C2 Sequence D
:95a::BUYR :95a::ACCW :95a::EXCH
:95a::DEAG :95a::BENM :95a::MEOR
:95a::DECU :95a::PAYE :95a::MERE
:95a::DEI1 :95a::DEBT :95a::TRRE
:95a::DEI2 :95a::INTM :95a::VEND
:95a::PSET   :95a::TRAG
:95a::REAG    
:95a::RECU    
:95a::REI1    
:95a::REI2    
:95a::SELL    

C5 

If a qualifier from the list Deliverers is present in a subsequence C1, 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 C, the following scenarios must be validated:

If a qualifier from the list Receivers is present in a subsequence C1, 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 C, 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)
DEAG Delivering Agent REAG Receiving Agent

C6 

In subsequence C1, if field :95a::PSET is present, then field :97a::SAFE is not allowed in the same subsequence .(Error code(s): E52).

Subsequence C1
if field :95a::PSET is ...
Subsequence C1
then field :97a::SAFE is ...
Present Not allowed within the same occurrence
Not present Optional

C7 

If field :22F::DBNM//VEND is present in sequence C, then a vendor must be specified; that is one occurrence of sequence D must contain field :95a::VEND (Error code(s): D71).

If sequence C is ... And in sequence C
if field :22F::DBNM//VEND is ... (*)
Then sequence D is ... And in one occurrence of sequence D
field :95a::VEND is ...
Present Present Mandatory, that is, must be present minimum once Mandatory
Not present Optional Optional
Not present Not applicable Optional Optional

(*) if the Data Source Scheme is present in field :22F::DBNM//VEND then the conditional rule does not apply.

C8 

In sequence D, if field :95a::EXCH Stock Exchange or :95a::TRRE Trade Regulator is present, then field :97a:: is not allowed in the same sequence (Error code(s): E63).

Sequence D
if field :95a::EXCH or TRRE is ...
Sequence D
then field :97a:: is ...
Present Not allowed within the same occurrence
Not present Optional

C9 

In sequence B, field :94a::TRAD must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::TRAD) (Error code(s): E99).

In sequence B, field :94a::SAFE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::SAFE) (Error code(s): E99).

In each occurrence of subsequence B1, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE) (Error code(s): E99).

In each occurrence of subsequence C1, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE) (Error code(s): E99).

In each occurrence of subsequence C2, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE) (Error code(s): E99).

In each occurrence of sequence D, field :95a::ALTE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:95L::ALTE) (Error code(s): E99).

C10 

In each occurrence of sequence D, if field :95a::ALTE is present with format option L, then field :95a::MEOR and field :95a::MERE must not be present in the same occurrence of the sequence (Error code(s): E88).
