EDI x12 Batching Just through Map

Question

Hi - I have a FlatFile message coming in, which is mapped to EDI x12 837 schema (containg ST/SE).
When I test the Map which input file , only first ST/SE is created and all other records are skipped. Is there any property in the schema that I need to change so that while I do Test  Map, all records appear instead of just one ?

That's actually how the EDI schemas work because that's how EDI transactions are structured with ST/SE at the top level.  Only in an Functional Group, GS/GE, can you have multiple ST/SE's.  Interchange batching ISA/GS/GE/IEA are handled by the
Batching Orchestration.
A HIPAA 837 contains multiple claims because of the looping at the 2000A thru 2300 levels.
If you have an input with multiple claims, you have three choices:
Link your map to loop at 2000A (or 2300 if 2000A/B are the exact same for each Claim).  This will give you one message, ST/SE, with multiple claims.
Debatch your incoming file into individual claims, map/process/etc, then use BizTalk EDI Batching to assemble the out going Interchange.
Map Directly to the Interchange Schema.  For this to work, it requires some hand coding in places.
Couple of notes from experience:
#2 is the my preferred way even though it creates individual ST/SE's for each claim.  Some gripe that defeats the purpose of the looping in the 837 but it's actually more in line with EDI and business transactions in general.  However some receivers
can't accept this for legacy software reasons.
If you have to make a single ST/SE with multiple claims, it's much easier to just loop at 2000A for every claim in the incoming batch, even if there is duplicate data in 2000A's.  The 1k you might save in the EDI is not worth the effort, programming
or CPU, to resequence by Billing Provider.
