What’s the best approach to handling slowly changing dimensions (SCD) in Power BI?
In my Power BI project, I’m dealing with slowly changing dimensions (SCD), and I’m unsure about the most effective way to handle changes in historical data over time. I need to maintain accurate reporting for different time periods, including tracking changes in attributes like customer address or product category. What strategies can I use to model SCDs effectively in Power BI to preserve historical data while keeping the reporting performance optimal?
