Imagine you have several sites, each with some assets underneath them in the hierarchy. Each asset is based on the "Press" template, and each site is based on the "Site" template. You'd like to configure an attribute on each site that shows the total number of tires produced for presses underneath, adding up the current values of "Tires Produced" attributes for all child presses once per day at midnight. How would you do this?Create individual analysis on each site$-$level element. Configure the rollup to find attributes fitting the pattern $"\%$SiteID$\%.$Press$\mathrm{.}01|$Tires Produced", then output the Sum to a new attribute. Set them to trigger at midnight.

Configure a formula data reference on the site template. Configure the "Tires Produced" attribute for each press to be an input to the formula, then add them all together.

Edit the "Site" template, adding an Rollup analysis. Configure the rollup to find attributes with the name "Tires Produced", and output the Sum to a new attribute. Set it to trigger daily at midnight.

Create a new event frame template, then create a PIPoint data reference attribute template inside it$.$ Point the PIPoint data reference to the attribute $".\backslash$Elements$[.]|$Tires Produced" and leave all other boxes as default. Configure an Event Frame Generation attribute, and have it trigger to start at midnight every day, and stop $24$ hours later.
