To replace the byte size error do I use the binary or ascii format.
if you received the byte size error, (1) ftp the file from the server using binary mode and the byte size in the manifest should match the byte size of the file. (2) once you've submitted to the IRS, in order to submit another file you need to re-run the BN299 to obtain a new UUID for the file. From:
