Hi ,
i have got a requirement below to create reports in percentage using indicator in performance Analytics, they have provided below calculation . can you please tell me whether below requirement is possible to do or not. We need to achieve using SLA Table.
1. Response SLA – The response SLA is the percentage of incidents responded within the agreed SLA timeframe to the overall incidents handled by the group.
Hence, to calculate this for Database -L1
Formula for calculation:
Response SLA %= (Total number of incidents responded within the SLA timeframe)*100 / (Total number of incidents handled by Database -L1)
Please note : the denominator Incidents handled should include all the incidents where Database -L1 was the first assignment group, not necessarily be the resolver group.
2. Resolution SLA – The response SLA is the percentage of incidents resolved within the agreed SLA timeframe to the overall incidents resolved by the group.
Formula for calculation:
Resolution SLA %= (Total number of incidents resolved within the SLA timeframe)*100 / (Total number of incidents resolved by Database -L1)
3. First Call Resolution (FCR) – FCR measures how many incident were resolved on the first contact.
Formula for calculation:
FCR% = (Total number of incidents resolved on the first contact by Support L1)*100 / ( Total number of incidents handled by Database -L1 as the first assignment group)
Please note: the denominator Incidents handled should include all the incidents where Database -L1 was the first assignment group, not necessarily be the resolver group.
Solved! Go to Solution.

For your SLA by assignment group requirement, ensure you have the SLA breadowns plugin installed and add the breakdown to the SLA definitions you wish to have a breakdown of time-taken
Information will then be available in sla_breakdown_by_assignment and attribute the duration of an SLA to each assignment group.
For your response SLA, you're going to want to keep attaching SLAs on each re-assignment
https://www.servicenow.com/docs/csh?topicname=c_SLAProcessing.html&version=latest <- Understand how SLA conditions are evaluated
- Specifically, we want the restart and start condition to be true to attach a new SLA
I created the following SLA
As for the results: A new Incident Group Response SLA is attached for each assignment group change.
And because assignment group breakdown is enabled, within the Task SLA record there is a related list for the group
Or another view of the data

Can you share your SLA definition, including the stop stop, pause and reset conditions.
You just need to change the reset condition to create a new ACL on assignment group change

Hi Kieron,
Our SLA Definitions are configured as below.
Step: 1
I have an incident with Category as password reset and subcategory as Reset Team, because of assignment rules , the Assignment Group routing will be Support -L1 automatically and it was assigned to a user manually.
Screenshot 1:
Here is the SLA attached and Response SLA Achieved as it was assigned to a user. The resolution SLA is in progress. Here the assignment group for SLA Definition is Support - L1.
Screenshot 2:
Step 2:
The Support - L1 group reassigned to another correct group Support -L2.
Assignment Group changed from Support -L1 to Support -L2.
Screenshot 3:
Below are the SLA Definitions added and Assignment Group changes .
Screenshot 4:
For the above three SLA Definitions , the Assignment Group also changed from Support -L1 to Support -L2. we cannot see any data related to Support -L1 Group (refer screenshot 2 and screenshot 4)
Because of this change in assignment group in SLA Definition , we are not able to calculate the work done and achieved by Support -L1 team. As Priority 3 (4 hours) Response SLA is achieved by Support -L1 , Before the assignment group got changed in incident.
All these 3 SLA Definitions achievement is going for Support -L2.
Is there any way , can you suggest us , where we need to calculate the total Response or Resolution SLA 's achieved by Support -L1 Group by considering the above scenario.
Step3:
Here are the start , stop and pause condition for this Response SLA's
Start condition screenshot 5:
Pause condition:
No
Reset Condition:
No
Stop Condition:
Step4:
Here are the start , stop , Reset and pause condition for this Resolution SLA's
Start Condition screenshot 6:
Pause Condition:
Stop Condition
Reset Condition:
