How can Power BI consultants ensure data accuracy in reports?
Start by verifying data source connections and confirming data integrity before importing into Power BI consultant. Use Power Query for consistent data cleaning and transformation processes. Implement data validation techniques within the data model, such as range checks or consistency checks between related tables. Automate refresh schedules to ensure data stays up-to-date. Compare report data with source data to identify discrepancies. Involve business users in the validation process by testing reports with real-world scenarios. Regularly audit reports and data models to maintain accuracy as the business evolves.
