概要
Enables or modifies the referent fields so that you can manage referent information for the registered LRS event.
使用法
The tool enables the referent fields by allowing you to register the existing fields as the referent fields.
If referent fields are already enabled, then by default, the tool will populate the existing fields so that they can be modified.
The existing data in the referent fields is not validated or updated when you enable or modify the referent fields.
To disable the referent fields, use the Disable Referent Fields tool.

コードのサンプル
The following Python window script demonstrates how to use the EnableReferentFields tool in immediate mode to enable referent fields for an existing LRS event.
# Name: Enable_Referent_Fields_ex1.py
# Description: Enable referent fields for an existing LRS Event that already has referent fields configured.
# Requires: ArcGIS Location Referencing
# Check out license
arcpy.CheckOutExtension("LocationReferencing")
# Local variables:
inputEventFC = r"c:\EnableReferent\Py\EnableReferent.gdb\LRS"
fromReferentMethodField = 'FromRefMethod'
fromReferentLocationField = 'FromRefLocation'
fromReferentOffsetField = 'FromRefOffset'
toReferentMethodField = 'ToRefMethod'
toReferentLocationField = 'ToRefLocation'
toReferentOffsetField = 'ToRefOffset'
offsetUnit = 'FEET'
# Execute the tool
arcpy.EnableReferentFields_locref(inputEventFC, fromReferentMethodField, fromReferentLocationField,
fromReferentOffsetField, toReferentMethodField, toReferentLocationField,
toReferentOffsetField, offsetUnit)
# Check in license

The following stand-alone Python script demonstrates how to use the EnableReferentFields tool to modify referent fields for an existing LRS event that already has configured referent fields.
# Name: Enable_Referent_Fields_ex3.py
# Description: Modifies referent fields for an existing LRS Event that already has referent fields configured.
# Requires: ArcGIS Location Referencing
# Import arcpy module
import arcpy

toReferentMethodField = 'ToRefMethod2'
toReferentLocationField = 'ToRefLocation2'
toReferentOffsetField = 'ToRefOffset2'
# Execute the tool
arcpy.EnableReferentFields_locref(inputEventFC, '' , '' , '' , toReferentMethodField, toReferentLocationField, toReferentOffsetField)
# Check in license
