What is the best way to showcase the KPIs in SSRS?
KPIs are Key performance indicators. In SSRS, we can show case KPIs via Gauges or Indicators. Gauge helps us to show the relative data and Indicators can show case the data with icons.
We can also include the Indicators inside the Gauge panel. If you check out below link from Microsoft documents, you will be able to find the complete procedure to use indicators and gauge panel.
