Raw Reflections- Dimension and Measure definition

When we enable Raw reflection is it necessary to to define dimensions and measures?
In some cases when I go to Data-set reflections settings page I don’t see any dimensions and measures grouped automatically. In such cases should I drag the dimensions and measures explicitly under specific columns or system will automatically create reflections on top of entire data set?


Hi @Dinesh,

When building raw reflections, you do not specify dimensions and measures. The window you are seeing where you can drag and drop columns into either the Dimension or Measure categories is for the aggregate reflections. We have a useful white paper on building and managing reflections that you might want to check out: https://www.dremio.com/lp/data-reflections-best-practices
