• Hard to identify the failing table, causing delays and missed client deadlines.

Objectives

• Identify and resolve data refresh failures in Power BI reports and dashboards.

• Implement monitoring and alerting mechanisms to proactively detect refresh failures.
• Improve data pipeline stability to maintain report accuracy and user trust.
• Optimize data models and queries to reduce refresh time and failure risk.

Implementation

• Reviewed error messages in Power BI Service to identify root causes
• Updated data source credentials in Power BI Service under Data Source Settings
• Configured and tested the On-Premises Data Gateway (if used) to ensure reliable connectivity.
• Optimized DAX queries and data model to reduce refresh duration and load.
• Set up scheduled refresh with proper frequency and retry settings.
• Enabled email notifications for refresh failures to alert stakeholders.
• Used Power BI Activity Log and Gateway Logs for deeper diagnostics

Solution

• Centralized credentials using a Power BI gateway.
• Enabled failure alerts and used refresh history to track issues
