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, ie, Function of the Message (field 23G) is CANC, then subsequence A1 (Linkages) Linkages must be present at least once and a reference to the previous message must be specified in the message, and in one and only in one occurrence of A1, Linkage section, ie, field :20C::PREV must be present; consequently, minimum once in all other occurrences of A1, field :20C::PREV is not allowed that message (Error code(s): E08).

Sequence A if field :23G: is...	then subsequence A1 is...	and field :20C::PREV is...
Sequence A if field :23G: is...	then subsequence A1 is...	and in minimum one occurrence of subsequence A1 field :20C::PREV is...
CANC	Mandatory (minimum one occurrence of A1 must be present)	Mandatory in one occurrence of subseq. A1, and not allowed in all other occurrences of subseq. A1
NEWM	Optional	N.A.
CANC	Mandatory, ie minimum one occurrence of A1	Mandatory (note: it does not need to be present in all occurrences of A1)
Not CANC	Optional	Optional
