We use Power BI reporting connected to SSAS tabular models (live connection). We need the ability to export the data with ease to monitor the metrics. On the export from the drill through tab, Power BIlimits the data export to 150,000 rows or 16 MB of uncompressed data. The primary table being used in SSAS has ~7 Million rows and ~100 columns. Drill through for a month of data has ~130K rows and ~60 fields (columns + measures) based on the primary table from the dataset (which has a total of ~7 Million rows). We are currently exploring 3 options for data export:
SSRS reporting based on denormalized tables
Paginated reports in Power BI
Analyze in Excel (connection to the SSAS Model)
Need inputs on pros and cons of these approaches and the best way forward.
