Power BI semantic modeling, DAX, paginated reports and SSRS: practical guidance for enterprise reporting.

Most Power BI models fail at scale for the same three reasons: a shape that is not a star schema, measures copied dozens of times, and reports that need a new page for every metric. Calculation groups, field parameters and a few DAX disciplines fix all three.

Interactive dashboards did not replace the invoice, the statement or the regulatory filing. Here is where SQL Server Reporting Services and Power BI paginated reports still win, how to decide, and how to migrate without losing the pixel-perfect output your auditors expect.
