Risk lookup table is to get the risk value corresponding to the success probability
value and impact value.

sn_chg_probability_risk_lookup table is used to fetch the data to calculate the risk value of
the change request.

By default, there are nine records with all the possible mappings for Impact and Success
Probability along with their corresponding risk values.

Change manager can add new records and delete existing records in the table. The Check impact
and probability combination business rule validates the duplicate mapping entries.

Navigate to AllChangeAdministrationCalculated Risk Score.

All the risk calculating engines calculate their corresponding risk value, the system picks the
highest risk and defines the risk for the Change. You can modify the Risk values irrespective of
the values defined for Impact and Success probability.

You can view the success probability definition that has set the success probability on the
change request by accessing the sn_chg_probability_details table. This table can be accessed by
the users who has read access to the change requests.

On the change request form, in the Related Links, click
Calculate risk. The risk engines calculate the risk for the Change. Click
the icon against the Risk field to view the risk set for the Change.  
Click the icon against Calculated Risk Score to find which type of success probability definition is responsible to set the risk for the change. There are three types of calculated risk score:

* Calculated (Impact + Success Probability)
* Calculated (Impact + Change Success Score)
* Calculated (Impact + Change Model Success)
* Not set: When the risk is not evaluated
