Hi, It will be great if the generation of min-max values can be automated based on a global setting ( ability to select last 3,6 or 12 months data) . I am curious what happens to these hard coded min/max values when the database is set to generate min/max values from the frontend I will assume they are discarded since they reside in the same table? Or which takes precedence ?
Thanks. ................................................

Our use case was we wanted to restrict values between 0 and 31, and not do it with a validation rule, to provide visual clues during data entry. As an aside, one may also want to calculate these values and save them to the database. The current algorithm uses a standard deviation approach, which is problematic, in that in many cases the data which is typically observed does not follow a normal Gaussian distribution. Other statistical models often provide better estimates of the mix/max, but currently, cannot be calculated automatically by the system. If these values are calculated externally in some statistical package, they can be inserted back into the system (or even automated).

I don't know your use-case... but in general one might want to think twice before setting the same max value for all facilities, since they usually have very different catchment population and hence natural variations in numbers.
