Subtype

Disponible avec une licence Data Reviewer.

Summary

The Subtype check finds features with improper or null subtype values.

Overview

The purpose of the Subtype check is to find features that contain attribute values that are not defined for the subtype. This includes attribute values that are inconsistent with the subtype's defined values and optionally null attribute values.

Subtypes are a subset of features in a feature class, or objects in a standalone table, that share the same attributes. For example, features in the Bridge line feature class can be organized into separate subtypes for bridges, overpasses, and viaducts instead of combining them into one subtype.

Supported workflows

ArcGIS Data Reviewer checks support multiple methods for implementing automated review of your data. The following table identifies the supported implementation methods for this check:

Validation			Constraint
Reviewer batch job	Reviewer map rule	Attribute (validation) rule	N0
Yes	Yes	Yes (ArcGIS Pro 2.7 or later)

Remarque :

This check will not be supported in map rules in subsequent versions of ArcGIS Pro, you are strongly encouraged to use this check in attribute rule-based workflows.

Syntax

Parameter	Required	Description	Workflows
Input Layers/Stand-alone Tables	Yes	The input feature layers or stand-alone tables evaluated by the rule. Valid inputs for this rule type are feature layers and stand-alone tables. Click the Forward button to apply filtering to specific features in the feature layer or specific rows in the stand-alone table.	Validation (map rules)
Subtype	No	The subtype that the rule is applied to if the dataset has subtypes.	Validation (attribute rules)
Attribute	No	A query that identifies the features to which the rule is applied.	Validation (attribute rules)
Search for Null Values	No	Attribute values that are <Null> (no value) are returned as an error.	Validation
Title/Name	Yes	A unique title or name for the rule. This information is used to support data quality requirement traceability, automated reporting, and corrective workflows.	Validation
Notes/Description	No	Descriptive text of the error condition when noncompliant features are found. This information is used to provide guidance to facilitate corrective workflows.	Validation
Severity	No	Severity of the error created when noncompliant features are found. This value indicates the importance of the error relative to other errors. Values range from 1 to 5, with 1 being the highest priority and 5 being the lowest.	Validation
Tags	No	Tag property of the rule. This information is used in rule authoring and management workflows to support traceability and reporting of data quality requirements.	Validation

Notes

Keep the following in mind when using the check:

• Domain-restricted attributes for features or table records assigned to an invalid subtype can't be evaluated when using the Domain check. Evaluation of domain-restricted attributes is required once subtype-related errors are corrected.
• When this check is authored as an attribute (validation) rule, the Attribute filter parameter is limited to comparison (=, <>, >, <, >=, <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, IS NULL) operators.
• When this check is authored as a map-based rule, verify that filter parameters using database-specific SQL functions are the same as from those supported in your production environment.
