Calculated Driver

A calculated driver is a labor driver that uses numerical constants or mathematical formulas in the absence of static or volume drivers. 

There are times when you may want to create a formula to derive a driver value that is then applied to the standard.  We created Calculated Drivers to help fulfill these need.  For example:  We want Opus to calculate the ratio between one static driver and another.  To do this we would create a calculated driver with a formula such as: [Stat Driver 1]  / [Stat Driver 2].  The result for this formula will be calculated on the fly and applied to the linked standard each time a validation or export is run.  As the Stat Driver 1 and Stat Driver 2 values vary by location and date, so will the calculated driver output and ultimately the standards output.  More complex formulas involving multiple drivers and math operations may also be created.
