I would like to calculate the number of days an item has aged. We don't currently use a "closed" date field, but rely on last modified.
=IF(Responsible1 = "Closed", NETDAYS(Created1, Modified1), NETDAYS(Created1, TODAY()))
Is there any way to add a formula to a column without triggering the last modified system field to update? This formula is pretty cool except when I add it, all of the last modified dates change to now, which defeats the purpose of the formula.
