Evaluate Part Count

Available with ArcGIS Pro Standard and Data Reviewer licenses.

Summary

The Evaluate Part Count check returns polygon and polyline features with part counts that are within a specified range.

Supported workflows

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

Workflow	Supported	Licensing
Validation attribute rule	Yes (ArcGIS Pro 2.5 and ArcGIS Enterprise10.8 or later)	Available with ArcGIS Pro Standard and Data Reviewer license
Constraint attribute rule	Yes (ArcGIS Pro 2.4 or later)	Available with ArcGIS Pro Standard and Data Reviewer license
Run Data Checks	Yes (ArcGIS Pro 3.5 or later)	Available with Data Reviewer license

Overview

The Evaluate Part Count check searches for features that contain part counts that are within a specified range. For example, if you search for all road features with more than two parts, all road features with three or more parts would be returned.

When configured as a constraint rule, an error notification is returned when a feature that contains the number of parts specified in the rule is created or modified.

When configured as a validation rule, an error is created for each feature that contains a part count within the specific range.

Attribute Rule syntax

The following table describes the validation and constraint attribute rule parameters:

Parameter	Required	Description	Workflow
Subtype	No	The subtype(s) to which the rule is applied.	Constraint
			Validation
Attribute	No	A query that identifies the features to which the rule is applied.	Validation
Number of Parts	Yes	The query that is applied to the count of a feature's parts. Any feature with a part count that matches what is defined in the rule is returned as an error. Is equal to—The number of parts is equal to the specified value. For example, if the value is 10, features with 10 parts are returned as results. Is not equal—The number of parts is not equal to the specified value. Is less than—The number of parts is less than the specified value. Is less than or equal to—The number of parts is equal to or less than the specified value. Is greater than—The number of parts is greater than the specified value. Is greater than or equal to—The number of parts is equal to or greater than the specified value. Is between (including bounds)—The number of parts is between or equal to the lower bound (minimum) and upper bound (maximum) values. Is between (excluding bounds)—The number of parts is between the lower bound (minimum) and upper bound (maximum) values. Is not between (including bounds)—The number of parts is not between or equal to the lower bound (minimum) and upper bound (maximum) values. Is not between (excluding bounds)—The number of parts is not between the lower bound (minimum) and upper bound (maximum) values. More input is required if you choose an operator with upper and lower bounding values.	Constraint
			Validation
Triggers	Yes	The editing events that trigger the rule to take effect. Insert—Triggers the rule when a new feature is added. Update—Triggers the rule when a feature is updated. Delete—Triggers the rule when a feature is deleted.	Constraint
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.	Constraint
			Validation
Description	No	A description of the error you define when a noncompliant feature is found. This information is used to provide guidance for corrective workflows.	Constraint
			Validation
Severity	No	The severity of the Reviewer result 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	The tag property of the rule. This information is used in rule authoring and management workflows to support traceability and reporting of data quality requirements.	Constraint
			Validation

Run Data Checks syntax

The following table describes the Run Data Checks parameters:

Parameter	Required	Description
Input Feature	Yes	The input feature layer that is evaluated by the rule. Note: You can disable a map selection or layer definition query using the toggle button that honors the selection or filter before evaluation. Layer definition queries that include a spatial clause are not supported.
Attribute Filter	No	A query that identifies the features to which the rule is applied.
Number of Parts	Yes	The query that is applied to the count of a feature's parts. Any feature with a part count that matches what is defined in the rule is returned as an error. Is equal to—The number of parts is equal to the specified value. For example, if the value is 10, features with 10 parts are returned as results. Is not equal—The number of parts is not equal to the specified value. Is less than—The number of parts is less than the specified value. Is less than or equal to—The number of parts is equal to or less than the specified value. Is greater than—The number of parts is greater than the specified value. Is greater than or equal to—The number of parts is equal to or greater than the specified value. Is between (including bounds)—The number of parts is between or equal to the lower bound (minimum) and upper bound (maximum) values. Is between (excluding bounds)—The number of parts is between the lower bound (minimum) and upper bound (maximum) values. Is not between (including bounds)—The number of parts is not between or equal to the lower bound (minimum) and upper bound (maximum) values. Is not between (excluding bounds)—The number of parts is not between the lower bound (minimum) and upper bound (maximum) values. More input is required if you choose an operator with upper and lower bounding values.
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.
Extent	Yes	Visible Extent—Evaluate the visible extent of the map. Full Extent—Evaluate the full extent of the data.

Notes

Keep the following in mind when using the check:

• Polygon and polyline features are supported with this check.
• The Attribute filter parameter is limited to comparison (=, <>, >, <, >=, and <=) and logical (AND/OR, IN/NOT IN, LIKE/NOT LIKE, and IS NULL) operators.
• The Attribute filter parameter does not support the following field types: Big Integer, Date Only, Time Only, and Timestamp Offset. If selected, the row header is marked in red and does not allow the rule to be saved.
