Let's set up SLA durations for resolving issues for different SLA's.

To set up SLA

1. go to the Administration > Custom fields menu.:
2. add a new custom field with SLA type
   

3. Set up conditions for SLA levels: while creating a field - add it to the issue view screen. Then you need to set duration times for every SLA:

   
4. Go to Edit Set Up the Field:

For every SLA you should specify:

• SLA name (free text, for example: "SLA-1 Premium")
• SLA time interval in minutes
• Working Calendar (see Setting Up Work Time Calendar for SLA)
• Color Scheme (see Setting Up the Color Scheme for SLA)
• Condition (JQL-query)
