Can two services have the same IDs if they refer to a parent transaction?
The services within a statement are identified by both “bankServiceID” and the “subServiceCode” elements. Thus “bankServiceID” can have duplicates as long as, for those same duplicate elements, different “subServiceCode” values are specified. It has to be noted that, it should not be assumed that the “serviceDescription” elements are used by the receiving system to differentiate services must not be made.
