Set Subnetwork Definition (Utility Network)—ArcGIS Pro

Summary

Sets the domain network tier's properties for a subnetwork in a utility network.

The types of features that participate in a tier can be restricted by defining valid asset types from the device, line, junction, edge object, and junction object classes. Defining valid asset types helps enforce data correctness by limiting the types of features that can participate in a subnetwork for a specific tier.

Configuration parameters are used to set properties when a trace is executed on the subnetwork.

Usage

This tool also allows you to set and alter the tier's subnetwork definition. To alter the values of the tier's subnetwork definition, modify the parameter values and execute the tool again.
The network topology must be disabled.
The following requirements must be met when working with an enterprise geodatabase:
- The connected ArcGIS Enterprise portal account must be the portal utility network owner.
- The Input Utility Network parameter value must be from a database connection established as the database utility network owner.
- This tool must be connected to the default version when executed.

Parameters

Explanation

Data Type

Input Utility Network

The input utility network that contains the tier's subnetwork.

Utility Network; Utility Network Layer

Domain Network

The domain network that contains the tier.

String

Tier Name

The name of the tier that contains the subnetwork.

String

Support Disjoint Subnetwork

Specifies whether the input tier will support disjoint subnetworks. Disjoint subnetworks are two or more subnetworks that belong to the same tier and have the same subnetwork name but are not traversable. This parameter is only available for tiers in domain networks with a partitioned tier definition. This parameter is checked for tiers in a domain network with a hierarchical tier definition to support disjoint subnetworks.

Checked—The input tier will support disjoint subnetworks.
Unchecked—The input tier will not support disjoint subnetworks. This is the default.

Boolean

String

Valid Device Subnetwork Controllers

(Optional)

The asset group/asset type pairs identified as valid device subnetwork controllers in the subnetwork.

String

Valid Lines

(Optional)

The asset group/asset type pairs identified as valid lines for the subnetwork.

String

String

Summaries

(Optional)

Sets the summary attribute field to store function results when inserting or updating SubnetLine features.

Summaries components are as follows:

Function—Choose from a number of calculation functions.
Attribute—Filter by any network attribute defined in the system.
Filter Name—Filter the function results by attribute name.
Filter Operator—Choose from a number of operators.
Filter Type—Choose from a number of filter types.
Filter Value—Provide a specific value for the input filter attribute.
Summary Attribute—The field in the SubnetLine feature class that will persist the function result. Depending on the selected function and network attribute type, only the applicable type of user-added subnetwork attributes will be valid for this parameter. If a field to store the summary result does not exist in the SubnetLine feature class, the Add Field tool can be used to create one. A field can only support the result of one summary; each summary requires its own field in the SubnetLine feature class. See the following matrix of valid field types for the summary attribute field based on the function chosen:

Condition Barriers

(Optional)

Sets a traversability barrier condition on features based on a comparison to a network attribute or check for a category string. A condition barrier uses a network attribute, an operator and a type, and an attribute value. For example, stop a trace when a feature has the Device Status attribute equal to the specific value of Open. When a feature meets this condition, the trace stops. If you're using more than one attribute, you can use the Combine using parameter to define an And or an Or condition.

Condition barrier components are as follows:

Name—Filter by any network attribute defined in the system.
Operator—Choose from a number of operators.
Type—Choose a specific value or network attribute from the value that is specified in the Name parameter.
Value—Provide a specific value for the input attribute type that would cause termination based on the operator value.

Value Table

Function Barriers

(Optional)

Sets a traversability barrier on features based on a function. Function barriers can be used to do such things as restrict how far the trace travels from the starting point, or set a maximum value to stop a trace. For example, the length of each line traveled is added to the total distance traveled so far. When the total length traveled reaches the value specified, the trace stops.

Function barrier components are as follows:

Function—Choose from a number of calculation functions.
Attribute—Filter by any network attribute defined in the system.
Operator—Choose from a number of operators.
Value—Provide a specific value for the input attribute type that, if discovered, will cause the termination.
Use Local Values—Calculate values in each direction as opposed to an overall global value, for example, a function barrier that is calculating the sum of Shape length in which the trace terminates if the value is greater than or equal to 4. In the global case, after you have traversed two edges with a value of 2, you have already reached a Shape length sum of 4, so the trace stops. If local values are used, the local values along each path change, and the trace continues.
- Checked—Local values will be used.
- Unchecked—Global values will be used. This is the default.

The function barrier Function value options are as follows:

Minimum—The minimum of the input values.

propagators [[Attribute, Substitution Attribute, Function, Operator, Value, Propagated Attribute],...] (Optional)	Specifies the network attributes to propagate as well as how that propagation will occur during a trace. Propagated class attributes denote the key values on subnetwork controllers that are disseminated to the rest of the features in the subnetwork. For example, in an electric distribution model, you can propagate the phase value. Propagators components are as follows: Attribute—Filter by any network attribute defined in the system. Substitution Attribute—Use a substituted value instead of bitset network attribute values. Substitutions are encoded based on the number of bits in the network attribute being propagated. A substitution is a mapping of each bit in a phase to another bit. For example, for Phase AC, one substitution could map bit A to B and bit C to null. In this example the substitution for 1010 (Phase AC) is 0000-0010-0000-0000 (512). The substitution captures the mapping so you know that Phase A was mapped to B and Phase C was mapped to null and not the other way around (that is, Phase A was not mapped to null and Phase C was not mapped to B). Function—Choose from a number of calculation functions. Operator—Choose from a number of operators. Value—Provide a specific value for the input attribute type that would cause termination based on the operator value. Propagated Attribute—The name of the field in the network class that is used to store the calculated propagated values. The field type should be the same as the field type of the network attribute chosen for the Attribute value. The propagators function value options are as follows: PROPAGATED_BITWISE_AND—Compare the values from one feature to the next. PROPAGATED_MIN—Get the minimum value. PROPAGATED_MAX—Get the maximum value. The propagators operator value options are as follows: IS_EQUAL_TO—The attribute is equal to the value. DOES_NOT_EQUAL—The attribute is not equal to the value. IS_GREATER_THAN—The attribute is greater than the value. IS_GREATER_THAN_OR_EQUAL_TO—The attribute is greater than or equal to the value. IS_LESS_THAN—The attribute is less than the value. IS_LESS_THAN_OR_EQUAL_TO—The attribute is less than or equal to the value. INCLUDES_THE_VALUES—A bitwise AND operation in which all bits in the value are present in the attribute (bitwise AND == value). DOES_NOT_INCLUDE_THE_VALUES—A bitwise AND operation in which not all of the bits in the value are present in the attribute (bitwise AND != value). INCLUDES_ANY—A bitwise AND operation in which at least one bit in the value is present in the attribute (bitwise AND == True). DOES_NOT_INCLUDE_ANY—A bitwise AND operation in which none of the bits in the value are present in the attribute (bitwise AND == False).

update_structure_features (Optional)	Specifies whether the update subnetwork process will update the supported subnetwork name attribute for structure network containers. UPDATE—The structure network containers will be updated. This is the default. NOT_UPDATE—The structure network containers will not be updated. Note: This parameter requires a Utility Network Version value of 4 or later.	Boolean
update_container_features (Optional)	Specifies whether the update subnetwork process will update the supported subnetwork name for domain network containers. UPDATE—The domain network containers will be updated. This is the default. NOT_UPDATE—The domain network containers will not be updated. Note: This parameter requires a Utility Network Version value of 4 or later.	Boolean
edit_mode_for_default_version (Optional)	Specifies the edit mode that will be used for subnetwork updates on the default version and with file and mobile geodatabases. WITHOUT_EVENTING—Eventing will not be used for subnetwork updates on the default version or in a file or mobile geodatabase. This edit mode updates the subnetwork name and propagated values in place. This is the default. WITH_EVENTING—Eventing will be used for subnetwork updates on the default version and in a file or mobile geodatabase. This edit mode executes geodatabase behavior (for example, attribute rules, editor tracking, and so on) when the subnetwork is updated and updates the subnetwork name and propagated values for all applicable features and objects. Note: This parameter requires a Utility Network Version value of 4 or later.	String
edit_mode_for_named_version (Optional)	Specifies the edit mode that will be used for subnetwork updates on a named version. WITHOUT_EVENTING—Eventing will not be used for subnetwork updates on named versions. This edit mode updates the subnetwork name and propagated values in place for features and objects edited in the version. This is the default. WITH_EVENTING—Eventing will be used for subnetwork updates on named versions. This edit mode executes geodatabase behavior (for example, attribute rules, editor tracking, and so on) when the subnetwork is updated and updates the subnetwork name and propagated values for all applicable features and objects. Note: This parameter requires a Utility Network Version value of 4 or later and is only applicable to enterprise geodatabases.	String
valid_junctions [valid_junctions,...] (Optional)	The asset group/asset type pairs identified as valid junctions for the subnetwork. Note: This parameter requires a Utility Network Version value of 4 or later.	String
valid_junction_objects [valid_junction_objects,...] (Optional)	The asset group/asset type pairs identified as valid junction objects for the subnetwork. Note: This parameter requires a Utility Network Version value of 4 or later.	String
valid_junction_object_subnetwork_controller [valid_junction_object_subnetwork_controller,...] (Optional)	The asset group/asset type pairs identified as valid junction object subnetwork controllers for the subnetwork. Note: This parameter requires a Utility Network Version value of 4 or later.	String
valid_edge_objects [valid_edge_objects,...] (Optional)	The asset group/asset type pairs identified as valid edge objects for the subnetwork. Note: This parameter requires a Utility Network Version value of 4 or later.	String
manage_subnetwork_isdirty (Optional)	Specifies whether the Is dirty attribute in the subnetworks table will be managed by the update subnetwork operation. If no subnetwork controllers are defined for the tier, this parameter uses the NOT_MANAGE option. MANAGE—The Is dirty attribute will be managed by the update subnetwork operation. This is the default. NOT_MANAGE—The Is dirty attribute will not be managed by the update subnetwork operation. Note: This parameter requires a Utility Network Version value of 5 or later.	Boolean
include_containers (Optional)	Specifies whether the container features and objects will be included in the trace results. INCLUDE_CONTAINERS— Container features and objects will be included in the trace results. EXCLUDE_CONTAINERS— Container features and objects will not be included in the trace results. This is the default. This parameter requires a Utility Network Version value of 5 or later.	Boolean
include_content (Optional)	Specifies whether the trace will return content of containers in the results. INCLUDE_CONTENT— Content of container features and objects will be included in the trace results. EXCLUDE_CONTENT— Content of container features and objects will not be included in the trace results. This is the default. This parameter requires a Utility Network Version value of 5 or later.	Boolean
include_structures (Optional)	Specifies whether structure features and objects will be included in the trace results. INCLUDE_STRUCTURES— Structure features and objects will be included in the trace results. EXCLUDE_STRUCTURES— Structure features and objects will not be included in the trace results. This is the default. This parameter requires a Utility Network Version value of 5 or later.	Boolean
validate_locatability (Optional)	Specifies whether an error will be returned during a trace or update subnetwork operation if nonspatial junction or edge objects are encountered without the necessary containment, attachment, or connectivity association in their association hierarchy of the traversed objects. This option ensures that nonspatial objects returned by a trace or update subnetwork operation can be located through an association with features or other locatable objects. VALIDATE_LOCATABILITY—An error will be returned if nonspatial junction or edge objects are encountered without the necessary containment, attachment, or connectivity association in their association hierarchy of the traversed objects. DO_NOT_VALIDATE_LOCATABILITY—The trace will not check for unlocatable objects and will return results regardless of whether unlocatable objects are present in the association hierarchy of the traversed objects. This is the default. Note: This parameter requires a Utility Network Version value of 5 or later.	Boolean
