X.12 EDI Relational Condition Check in Seeburger EDI Adapter

Question

Hello,
We're in middle of implementing ANSI X.12 EDI message integration with
Seeburger BIC Module with SAP PI 7.0. In X.12 protocol, there are so called
Relational Condition constraints on particular fields of a EDI segment. For
example, for EDI 850, the segment REF is bound by a constraint R0203;
segment FOB is bound by C0302, C0405, C0706, C0809.
Can anyone clarify that the standard EDI-To-XML 1:1 mapping generated by
Seeburger BIC Mapping Designer include these check rules or not ?
Are these check rules mandatory for all inbound EDI message processing
according to industry common practise ?
Thank you for any idea you may provide !

Hi Chirag,
For EDI 850, the segment REF has the following elements :
128
127
352
C040
The relational condition R0203 is bound to REF. This implies that elements 02 (ie 127) and 03 (ie 352) are Required, meaning at least one of both fields must exist.
The incoming EDI 850 data is validated by this rule.
Segment REF has several occurrances in the 850 schema and for all those occurances, the check rule applies.
For constraint C0302 on Segment FOB, it specifies that a "Conditional" condition
is bound on this segment, dictating that if element 03 exists, then element 02 must
also exist.
These constraints (aka Relational Condition) are expressed as "Syntax Notes"
on segments  for a particular X.12 EDI message type.
