If the message is a cancellation, ie, 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 in 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).
If the message is a cancellation, ie, Function of the Message (field 23G) is CANC, then a reference to the previous message must be specified in the Linkage section, ie, field :20C::PREV must be present minimum once in that message (Error code(s): E08).
