“The document is not being recognized…”
Focus on getting TN to recognize the doc type first, then you can work on the identifiers (if necessary).
It’s possible that your edits caused end-of-line markers to be added to your file. For EDI, this can be a bad thing especially on windows. The segment delimiter can only be a single character. If you used Notepad or some similar editor then it might have placed a CR/LF pair on each line–this will negatively impact the parser.
Terminology alert: reprocess and resubmit have very specific meanings and differing behavior within TN. Are you editing the document and resending it to TN for processing? When you say you are “reprocessing” what specifically are you doing?
