I can choose only business hours or calendar hours in SLA policy. How add other hours or my business hours? I have added a profile with business hours. I can't choose it from the menu shown in the attachment.
@Lukasz, my understanding of the business hours in the SLA's, is that it's connected to the group that gets assigned to a ticket. I.e. you can connect different business hours to different groups, and then depending on what group you assign a specific ticket to, the business hours for that group will get applied.
