How to use the draw categories function in ArcGIS Pro

PatriciaKingston

In ArcMap, we created category rules within the layer properties under the Symbology tab using options such as “Draw categories by matching field values to symbols in a style” or “Draw categories using unique values combining up to 3 fields”.

What equivalent function or workflow in ArcGIS Pro can be used to achieve the same result?

There's a couple ways to accomplish this:
1.  In ArcMap, create a layer file (*.lyr) from the layer in the Data Frame that has your predefined category rules.  Then in ArcGIS Pro, add that layer to a new map view and use the Apply Symbology From Layer (Data Management Tools) | ArcGIS Pro documentation to recreate the layer symbology in ArcGIS Pro.
2.  Or in ArcGIS Pro, use the Unique Values option and set the attribute field for Field 1.  Then click Add Field for Fields 2 and 3.
