Handling triggers for automation

Automation begins with triggers, and Power Automate offers a variety of triggers that can initiate workflows based on specific events. In the context of data cleaning for Power BI, triggers can be designed to activate when new data is added or modified or when certain conditions are met.

For instance, you can set up a trigger that initiates a data cleaning process whenever new data is ingested into your data source. This ensures that your data is consistently cleaned and prepared whenever there are updates, saving you time and ensuring the reliability of your reports.

Here’s a screenshot showing the type of triggers available specifically for Power BI within Power Automate:
