Re: ISA16 - sub element delimiter
A sub-element separator separates sub-elements in a compound element. These
are used extensively in EDIFACT, but not so much in X12. For example, the
REF segment has for elements (funny your customer should have a problem
with the REF):
REF01 - Ref ID qualifier (element ID 128)
REF02 - Ref ID (element ID 127)
REF03 - Description (element ID 352)
REF04 - Ref ID (element ID C040)
The last element is a compound element which contains 6 subelements - 3
pairs of Ref ID Qualifiers and Ref IDs.
The element separator separates REF01, REF02, REF03 and REF04, and the
subelement separator separates the subelements in REF04. If the element
separator is "*", the subelement separator is ">", and segment terminator
is "~", the REF can look like:
REF*PK*1234**BM>4321~
The usage of the subelement separator by your customer's trading partner is
completely incorrect, as the REF02 is not a compound element.
