What is working for me is....
Prepare the T4. Or the T5
Go into the Efile options and change the transmitter number to the client's business number, including RP0001 (I have not have to change this in this location to RZX001 for T5; RP0001 works fine here)
Tell the software to efile the return. Confirm that I am efiling a T4 or a T5. Once the software generates an XML file DO NOT continue in the software. If you do, the you do need a Web Access Code (WAC) which I do not have for most of my clients. Make a note of the location of the XML file, or move the XML file to another location if you wish.
On a browser log in to Represent a Client and then enter the client's business number in order to access their account (for which I have previously been authorized).
Go in the Payroll account (to file a T4) or the Information Slips section (to file a T5)
Tell the account that you want to file a return. As you go through the process you will upload the XML file that you just generated. You will not need a WAC.
You will be successful
Having said all of that, it is stupid that the Profile software is making us change the Transmitter number in the options section. The software should just be picking that number up from the business number on the information page. Simple solution to a problem that is causing grief for so many people.
