Hello Marc,

Yes . You are correct.

I will sent a HL7 message from a router and Flat records from another router. These two routers points to a single TCP Operation.

Receiving system will receive a HL7 message and a Flat record as you mentioned in a single TCP service.

Ex:

MSH|^~\&||HC6|||||MDM^T02|||2.5 EVN|T02|20180117094500 PID|||LD572046^^^HC6^MR||Smith^John||19301019|M|||1 Memorial Drive^^Cambridge^MA^02142||||||||063070516 PV1||O|||||ISCGP001^Moore^James|||||||EO|||||HSVN00006|||||||||||||||||||||||||20180117094500|20180117094500 TXA||Progress note||201801170945|JJ021^James^John||||ISCGP001^Moore^James|||19815952^TRANS OBX||FT|RTF^TRANS||Patient complaining of pain in right big toe.

FlatFileRow1Field1,FlatFileRow1Field2,FlatFileRow1Field3

FlatFileRow1Field1,FlatFileRow1Field2,FlatFileRow1Field3

...etc

Receiving system accepts both HL7 Messages and Flat records in a single TCP service.

Please let me know if  need more information.

Many Thanks,
