+Set Incident Priority Critical
+
+This UI Action sets current incident record as priority as Critical.
+
+When clicked
+Below Conformation message will be displayed to the user as below
+"Are you sure you want to set priority as Critical?"
+
+If user selects cancel nothing will happen.
+
+If user selects confirm then
+a) It sets the Priority of the current Record as 1-Critical by setting Urgency and Impact as 1-High.
+b) It also sets 'assigned_to' field as 'logedin user'.
+c) It also upends the description as "Priority is set to Critical by 'logedin User'".

+Unless you submit or update the record, field values will not be updated in the database table records.
+
+You can use this as reference to set other field values as well.
