Hello @JohnEJasinski ,
Using the Duration and especially the Business Duration fields is no longer recommended, as SLAs provide a better alternative that gives more control over the schedules and time zones involved in the calculation.
If you want to go ahead with using the duration fields you can create a Business Rule as shown below:
Advanced Script:
(function executeRule(current, previous /*null when async*/ ) {
current.business_duration = gs.calDateDiff(current.opened_at.getDisplayValue(), current.closed_at.getDisplayValue(), false);
current.calendar_duration = gs.dateDiff(current.opened_at.getDisplayValue(), current.closed_at.getDisplayValue(), false);
})(current, previous);
Regards,
Robert
