Excel Data Models are a powerful feature that allows users to analyze large datasets efficiently. However, they're not just about hierarchies! Data models can include complex relationships and calculated columns, which can significantly enhance data analysis capabilities. Users can create measures or KPIs, helping to derive insights that are both actionable and easily digestible for stakeholders. When it comes to common misunderstandings, many users believe once they set up their hierarchy, it’s fixed forever. However, hierarchies can be modified! You can easily add or remove levels depending on your analytical needs. Just remember to review your relationships and ensure they still make sense after making changes. So don’t be afraid to experiment and optimize your data structure!
