The issue was with the 'Classification' value(static) defined in the event rule. 3. When the event was being processed, the system couldn't find the static value in choice list configured for 'Classification'. 4. The 'Classification' value should be an integer. The system will pick the mapping value from sys_choice table. Resolution Modified the event rule classification field value to ${classification}. Eg: The raw value from the event is '0'
