CSV to HL7 in Mirth - Issue with extraneous information HL7 output

[njpowell218]

I have a channel creating HL7 messages from a csv file which is working successfully with one exception. In each output file I am getting the first line of extraneous information shown in bold below that is not part of my HL7 message. I need to understand how this is getting there and how I can eliminate it.
Input: csv
123456,012345678,Testerson,Testy,H,2020-05-01,36,T2025,,32,12,48628

You assign tmp=msg

Instead put a stub MSH segment in the outbound message template and remove that line.

Perfect. That did it! Thank you so much for the Super Fast Response!!!

Next time post to discussions first. Your question was neither a bug nor feature request.
