Issue I printed T4's for one of my employer groups.  The Business Registration # does not show up on the T4's.  Where do I need to set this up in order for the Registration # to show up on the T4's?
Solution Suggestion 1:

Check the Identification No. has been filled in the Employer Reporting Authorities
Payroll > Employers > Payroll button > Reporting AuthoritiesFill in the Identification No.

Suggestion 2:

Also, it could be the print options selected for the T4A Report.

Payroll > Documents > T4A - Laser
Options tab > 'Employee Per Page'

One = Business No. appears on report 
Two = No Business No. on report

The theory behind this is that the government (2 per page) copy of the T4 needs the business number but individual employee don't.
