Hey...

I am trying to figure out the same thing. I do have a field that identifies whether a record is the Header (H), Detail (D) or Trailer (T). However, with that being said, the package still blows up on execution. It gets a validation error telling me that the value being applied to variable emailSubj (which is on that I use in my flow) is mismatched. However, I create a file without the header and trailer and it processes with now problems. So having a field to differentiate what TYPE of record each row is doesn't seem to help.
