GL65.5 Errors

I am using a Infor-provided IPA flow which drops a file into the /work/GL65CSV folder. It then attempts to execute a GL65.5 to import the CSV file.

I get an error every time in the Work Unit log: File has already been processed.

(I can also do this via Portal and get the same errors when executing GL65.5 directly without the IPA flow.)

When I look at the LAPM log, I see different errors:
1) "CSV Hdr Read Error: Fld Name A-N-Y--F-I-E-L-D--N-A-M-E Not Found"
2) File GL65CSV Already open in Mode "r"

Every field name I have in the first row is spelled out with hyphens in between.

I've got to be missing something obvious. Thank you for the help.
