Rollup fields/columns can be used to aggregate your data, using functions of SUM, COUNT, MIN, MAX and AVG. These are built in Dataverse, which means you can use them across Power Apps and Dynamics 365.
In this hands-on tutorial, I’ll show you how to build a new rollup field/column from scratch (using Accounts and Opportunities in the Dynamics 365 Sales app), how to add it to a form, and then how to test/recalculate the sum.
