Set Subtype Field (Data Management)
Summary
Defines the field in the input table or feature class that stores the subtype codes.
Usage
-
A feature class or table can have only one subtype field.
-
After a subtype field is set, subtype codes can be added to the feature class or table using the Add Subtype tool.
-
The subtypes of a feature class or table can also be managed in ArcCatalog. Subtypes can be created and modified using the Subtypes Property page on the dataset's Properties dialog box.

Code Sample
The following Python window script demonstrates how to use the SetSubtypeField function in immediate mode.
import arcpy from arcpy import env env.workspace = "C:/data/Montgomery.gdb" arcpy.SetSubtypeField_management("water/fittings", "TYPECODE")
The following stand-alone script demonstrates how to use the SetSubtypeField function as part of a workflow to add subtypes to a field.
