C1
At least one of the sequences B or D must be present (Error code(s): E47).
C2
At least one of the sequences C or E must be present (Error code(s): E48).
Note: ref. rule C3
C3
When the settlement method, ie, the second subfield of field 23A, is "NET", either sequence C or E must be present, but not both (Error code(s): E49).
Note: When the settlement method is NET, this rule takes precedence over rule C2.
C4
When the settlement method, ie, the second subfield of field 23A, is "NET", the payments block (i.e. fields 30F---57a) within sequence C or E must occur only once (Error code(s): E50).
i.e. field 18A in seq. C or E must be =1, refer to indexes 30 or 51, field 18A
NETWORK VALIDATED RULES (Error code(s): D96).
Note: ref. Rule C2 (seq. C or E must be present)
C5
When the settlement method, ie, the second subfield of field 23A, is "GROSS", the payments block (i.e. fields 30F---57a) within sequence C or E cannot occur more than three times (Error code(s): E51).
i.e field 18A must be <4, refer to indexes 30 or 51, field 18A
NETWORK VALIDATED RULES (Error code(s): D96).
Note: ref. rule C2 (seq. C or E must be present)
C6
The currency code of the fields 33F and 32H in sequence B must be the same. The currency codes of the fields 33F and 32H in sequence D must be the same (Error code(s): E38).
C7
The second intermediary field can only be used if two intermediaries are required. Thus, for all occurrences of the fields 56a and 86a, the following rules apply (Error code(s): E35):
C8
The related reference must be present for an amendment or cancellation. Thus, in sequence A, the presence of field 21 depends on field 22A as follows (Error code(s): D02):
C9
Taking into account C1:
The cap and floor rates are mandatory in the case of a cap, floor or collar otherwise they are optional. Thus, in sequences B and D, the presence of fields 37J and 37L depends on subfield 1 of field 23A in sequence A as follows (Error code(s): E39):
