C1 

Within each occurrence of subsequence A2a, the qualifier in field 24B must be the same as the code word (Status Code) used with the appropriate qualifier in field 25D of its surrounding subsequence A2 (Error code(s): E37).

In each occurrence of Seq. A2 Status
In each occurrence of Subseq. A2a Reason (if present) if field :24B:: is...	then in Seq. A2 Status, field :25D:: must be... (*)
:24B::CAND	:25D::IPRC//CAND or :25D::CPRC//CAND
:24B::CANP	:25D::CPRC//CANP
:24B::DEND	:25D::IPRC//DEND or :25D::CPRC//DEND
:24B::PACK	:25D::IPRC//PACK or :25D::CPRC//PACK
:24B::PEND	:25D::IPRC//PEND or :25D::EPRC//PEND
:24B::REJT	:25D::IPRC//REJT or :25D::CPRC//REJT

(*) if the Data Source Scheme is present in field :25D:: then the conditional rule does not apply.

C2 

If the message is an instruction status or a cancellation request status (:23G:INST or CAST), AND Sequence B is present, AND an instruction has been received (:25D::IPRC//NOIN is NOT present in the message), then sequence B should contain a CA option number and code (:13A::CAON and :22a::CAOP are mandatory) (Error code(s): D29).

In Seq. A if field :23G: is...	And Seq. B is...	And field :25D::IPRC//NOIN(in Subseq. A2) is...	then Seq. B, field :13A::CAON is...	And Seq. B, field :22a::CAOP is...
INST or CAST	Present	Not present in the message,or used with a DSS	Mandatory	Mandatory
		Present at least once in the message without DSS (*)	Optional	Optional
	Not present	n/a	n/a	n/a
EVST	n/a	n/a	n/a	n/a

(*) this condition takes precedence over the condition "Not present in the message, or used with a DSS".
