Common Pitfalls

• Pitfall: Misunderstanding context transition can lead to incorrect DAX results. To avoid this, always test measures in small tables and use CALCULATE with FILTER carefully.
• Pitfall: Overcomplicating relationships early can break visuals. Stick to star schemas and verify cardinality before adding calculated columns.
• Pitfall: Ignoring query folding risks slow reports. Always check the Applied Steps pane to confirm operations are pushed to the source database.
• Pitfall: Using calculated columns when measures suffice bloats models. Reserve columns for row-level logic and use measures for aggregations.
• Pitfall: Publishing without testing RLS rules exposes sensitive data. Always validate security filters with test accounts before sharing.
• Pitfall: Skipping documentation leads to unmanageable reports. Add descriptions to queries, measures, and visuals to aid future maintenance.
• Pitfall: Relying solely on default visuals limits impact. Learn at least two custom visuals to enhance storytelling and user engagement.
