Yes, the January 31, 2025 update CT80D, Update 2 is installed. The CRA representative said our software should not have anything in the Rep ID field but we cannot generate the file unless it has been filled in.

I just helped a client by installing the PU2 and the T4-T4A hotfix.  We used the BN15 option with the full CRA business number including the RT0001.  We left the Rep Id field blank.

We were able to create the file and upload it successfully and accepted by CRA.
