Understanding Calculated Columns in Dataverse by Expert

Let's illustrate these concepts: suppose we have a solution that maintains information about the cleaning of rooms, apartments, and residential buildings. In this data model, each room connects to an apartment, and each apartment connects to a building. The data is maintained with model-driven Power Apps. Individual rooms are marked as cleaned using mobile Power Apps. Now, if we want to show the number of cleaned rooms per apartment in the tools, easily done with a rollup column.

Similarly, for more precise data such as the cleaning percentage of rooms in an apartment, we create another summary column, and the percentage is calculated using the values of the previous columns. However, the values of the summary columns are not calculated in real time but in a scheduled task that runs 12 hours after the column is created and updated once an hour. The values can also be updated manually with the Recalculate button.

The post also talks about updating summary columns with Flow and how calculated columns can be used in Canvas Power Apps. It also covers the use of Power FX columns in preview mode. Remember, while using summary columns, they are not real-time which limits their uses.
