Hi,
Since you are using must be using pub.flatfile.convertToValues to covert the flat file to IS document by validating against schema, you need to provide record delimiter and field delimiters in the input signature of this service.
Please set the segment and line delimiter from you sample file, it should solve your problem. Wrote us back if still find some issue.
cheers!
