We have been uploading T4 for years with internet file transfer application with our BN and access code. With the lasted update from CRA we cant now do that with SAGE because the transmitter BN is only 9 characters and doesn't have the required information RP0001 to matter the login. We use other software and can file with but don't want to redo the T4s in it. We can file through Rep Client on the Clients that we have access with. Please let us know what you can do
