How do you ensure data accuracy and quality in your Power BI reports?

To ensure data accuracy and quality in my Power BI reports, I follow a few key practices. First, I validate the data sources and perform necessary data cleansing and transformation before loading it into Power BI. I carefully define relationships between tables to ensure data integrity. I also apply data validation techniques to identify and handle any discrepancies or outliers. Regularly reviewing and validating the data with subject matter experts was another important step to maintain accuracy. Lastly, I documented the data sources, transformations, and calculations used in the reports to ensure transparency and reproducibility.
