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).
If the instruction is against payment (:22H::PAYM//APMT) then it is mandatory to specify a Posting Amount (field :19A::PSTA). This rule applies to subsequence B1a2 (Error code(s): E83).
In each occurrence of subsequence B1a, in subsequence B1a2, the following Party Fields cannot appear more than once (Error code(s): E84):
Subsequence B1a2a
:95a::BUYR
:95a::DEAG
:95a::DECU
:95a::DEI1
:95a::DEI2
:95a::PSET
:95a::REAG
:95a::RECU
:95a::REI1
:95a::REI2
:95a::SELL
If a qualifier from the list Deliverers/1 is present in a subsequence B1a2a, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Deliverers/1 (see below) must be present (Error code(s): E86).
In other words, in subsequence B1a2, the following scenarios must be validated:
If :95a::DEI2 is present in subsequence B1a2a, then :95a::DEI1 must be present in another subsequence B1a2a.
If :95a::DEI1 is present in subsequence B1a2a, then :95a::DECU must be present in another subsequence B1a2a.
If :95a::DECU is present in subsequence B1a2a, then :95a::SELL must be present in another subsequence B1a2a.
If a qualifier from the list Receivers/1 is present in a subsequence B1a2a, in a field :95a::4!c, then all the remaining qualifiers following this qualifier in the list Receivers/1 (see below) must be present (Error code(s): E86).
In other words, in subsequence B1a2, the following scenarios must be validated:
If :95a::REI2 is present in subsequence B1a2a, then :95a::REI1 must be present in another subsequence B1a2a.
If :95a::REI1 is present in subsequence B1a2a, then :95a::RECU must be present in another subsequence B1a2a.
If :95a::RECU is present in subsequence B1a2a, then :95a::BUYR must be present in another subsequence B1a2a.
If the message is a cancellation, that is, 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 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).
In subsequence B1a2a, if field :95a::PSET is present, then field :97a::SAFE is not allowed in the same sequence (Error code(s): E52).
If in sequence A field :17B::CONS=Y, then in every occurrence of sequence B Sub-safekeeping Account, field :97a::SAFE and field :17B::ACTI are mandatory (Error code(s): E56).
This check only applies when sequence B Sub-safekeeping Account is present as per rule C1, that is, in sequence A, field :17B::ACTI=Y.
If the Activity Flag (field :17B::ACTI) in sequence B Sub-safekeeping Account indicates no information to be reported, that is, N, then subsequence B1 Financial Instrument must not be present. subsequence B1 Financial Instrument is otherwise mandatory (Error code(s): E69).
This check only applies when sequence B Sub-safekeeping Account is present per rule C1, that is, in sequence A, field :17B::ACTI=Y.
In each occurrence of subsequence B1a2, field :36B::PSTA cannot appear more than twice (maximum two occurrences). When repeated, one occurrence must have Quantity Type Code FAMT and the other occurrence must have Quantity Type Code AMOR (Error code(s): C71).
A reference to the previously received message must be specified for each transaction reported, that is in each occurrence of subsequence B1a Transaction, field :20C::RELA must be present in one and only one occurrence of subsequence B1a1 Linkages; field :20C::RELA is not allowed in all other occurrences of subsequence B1a1 (Error code(s): C73).
In sequence A, if field :95L::ALTE is present, then field :95a::ACOW must be present (Error code(s): E98).
In each occurrence of sequence B, if field :95L::ALTE is present, then field :95a::ACOW must be present (Error code(s): E98).
In each occurrence of sequence B, field :94a::SAFE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::SAFE) (Error code(s): E99).
In subsequence B1a2, field :94a::CLEA must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::CLEA) (Error code(s): E99).
In subsequence B1a2, field :94a::SAFE must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::SAFE) (Error code(s): E99).
In subsequence B1a2, field :94a::TRAD must not be present more than twice. When repeated, one and only one occurrence must be with format option L (:94L::TRAD) (Error code(s): E99).
