Summary
Appends routes from an input polyline into an LRS Network.
Note:
When the target layer is a feature service layer, the validation results for this tool are written to the ArcGIS Server directory. This file is automatically cleaned up in 10 minutes by default, which may not be enough time to process all of the validations and write them to your workstation running ArcGIS Pro. For larger data loads, it is recommended that you adjust the maximum file age to at least one hour.
Learn more about adjusting this server directory setting in Manager
Usage
An LRS dataset is required to run this tool. To create an LRS dataset, add the calibration point, centerline, and redline layers to a feature dataset; then run the Modify LRS tool with the geodatabase as the input.
This tool will create centerlines in the target LRS dataset as well as routes in the target LRS Network.
The output routes will have x-, y-, and z-values from the input polyline vertices, but no m-values will be appended.
If your source polyline feature class has editor tracking enabled, map the source editor tracking fields to the fields you will use for editor tracking in the LRS Network while editor tracking is disabled in the target.
Any new fields that will be used for field mapping should be created in the underlying LRS Network feature class before appending routes.
The spatial reference, XY resolution, and XY tolerance of the input polyline feature class and the target LRS Network must match.
A text log is written locally that states that the tool has been executed and contains information on any routes that failed validation. The tool messages provide the location of the text log, which is in the temporary directory.
The output of this tool is a modified LRS Network that has had routes appended and centerline features created.
When conflict prevention is enabled, the following are supported:
- If the routes to be appended are new, no locks will be acquired for those routes.
- For other load types, such as RETIRE_BY_ROUTE_ID and REPLACE_BY_ROUTE_ID, locks will be automatically acquired, if available.
- If the locks cannot be acquired, the tool will not run and will provide the text file of offending locks.
- If working in the default version, the locks acquired are released automatically when the tool finishes running successfully.
- If working in a child version, the acquired locks will remain in ON POST status after the tool completes. Post or delete the version to release the locks.
- If working in a child version and the execution of the tool is canceled by interruption, the locks are acquired and remain with the releasable status as Yes. The lock owner can release the lock.
Learn more about releasing locks in Pipeline Referencing or releasing locks in Roads and Highways.

If the target LRS Network is configured as a line network with support for a multifield route ID, the following parameters are not required for appending routes:
- Route Name Field
- Line Name Field
Syntax
arcpy.locref.AppendRoutes(source_routes, in_lrs_network, route_id_field, route_name_field, {from_date_field}, {to_date_field}, {line_id_field}, {line_name_field}, {line_order_field}, {field_map}, {load_type})| Parameter | Explanation | Data Type |
source_routes | The input from which the routes will be derived. The input can be a polyline feature class, shapefile, feature service, or LRS Network feature class. | Feature Layer |
in_lrs_network | The target LRS Network into which the routes will be loaded. | Feature Layer |
route_id_field | The field in the input polyline feature class that will be mapped to the LRS Network route ID. The field type must match the RouteID field type of the target LRS Network and must be either a string or GUID field type. If it is a text field, the field length must be shorter than or equal to the length of the target RouteID field. | Field |
route_name_field | The field in the input polyline feature class that will be mapped as the LRS Network route name. The field must be a string field, and the field length must be shorter than or equal to the length of the target route name field. | Field |
from_date_field (Optional) | A date field in the input polyline feature class that will be mapped as the From Date Field in the LRS Network . If the field is not mapped, a null value representing the beginning of time will be provided for all appended routes. | Field |
to_date_field (Optional) | A date field in the input polyline feature class that will be mapped as the To date in the LRS Network. If a To date field is not mapped, a null value representing the end of time will be provided for all appended routes. | Field |
line_id_field (Optional) | The field in the input polyline feature class that will be mapped as the LRS Network line ID. This parameter is only used if the target is an LRS line network. The field type must match the RouteID field type of the centerline sequence table and must be either a string of exactly 38 characters or a GUID field type. | Field |
line_name_field (Optional) | The string field in the input polyline feature class that will be mapped as the LRS Network line name. This parameter is only used if the target is an LRS line network. | Field |
line_order_field (Optional) | The long integer field in the input polyline feature class that will be mapped as the LRS Network line order. This parameter is only used if the target is an LRS line network. Learn more about line networks and line order in Pipeline Referencing or line networks and line order in Roads and Highways. | Field |
field_map (Optional) | Controls how attribute information in the source route fields is transferred to the input LRS Network. Fields cannot be added to or removed from the target LRS Network because the data of the source routes is appended into an existing LRS Network that has a predefined schema (field definitions). While you can set merge rules for each output field, the tool will ignore those rules. The ArcPy FieldMappings class can be used to define this parameter. | Field Mappings |
load_type (Optional) | Specifies how appended routes with measure or temporality overlaps with identical route IDs as Target Network records are loaded into the network feature class.
| String |
Derived Output
| Name | Explanation | Data Type |
| out_lrs_network | The updated LRS Network feature layer. | Feature Layer |
| out_details_file | The text file that details changes made by the tool. | Text File |
