C1 

If the Activity Flag (field :17B:ACTI) in sequence A General Information is N, then sequence B must not be present. Otherwise, sequence B is mandatory (Error code(s): E66).

Sequence A if field :17B::ACTI is...	Sequence B is...
N	Not allowed
Y	Mandatory

C2 

The 'Balance From' must be different from the 'Balance To': within each occurrence of subsequence B2 Sub-Balance, the Sub-Balance Type of field :93A::FROM must be different from the Sub-Balance Type of all occurrences of field :93A::TOBA in subsequence B2a Intra-Position Movement (Error code(s): E81).

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 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
