Modified the web application to fix the error encountered in adding the business unit and manager, the manager is not added along with the business unit, tested the modified web application, as per checking, it is now OK.
Tested the Report by Ticket Owner problem on why the ticket manager selection is not showing selection though it is showing on my local but not on the server, modified as well the business unit and ticket manager selection in Ticket Activity Log report, for separating the business unit selection from ticket manager selection.
