Hi @Nisha30 ,

If no schedule is specified, then the Business elapsed time is the same as the Actual elapsed time. This can be disabled by changing the com.snc.sla.always_populate_business_fields property to false in the SLA Engine. When this property is set to false, the Business fields will be 0 or empty.

For more understanding refer below thread which explains with example how Actual Time elapsed & Business time elapsed are calculated.
