MT 565 Network Validated Rules

C1 

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 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

C2 

In sequence D, if field :22F::CAOP//SPLI is present, then field :70E::INST is mandatory in the same sequence (Error code(s): E79).

Sequence D if field :22F::CAOP//SPLI is...(*)	then field :70E::INST is...
Present	Mandatory (i.e. minimum one occurrence)
Not present	Optional

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