I have a project where I will need to take an HL7 messages and transforms it into a multi-line flat file. I tried creating a complex record map but those require leading data to identify the record type I'm dealing with but based on the destination vendors spec they do not want any leading data prior to the actual data being sent. Also the lines in the output file require different pieces of data pull from different HL7 fields in the messages and in the third field in the flat file I need to generate a unique line number.
Any assistance would be greatly appreciated.
