# Path Search function

# Path Search function {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 2 minutes to read  
The Path Search function enables you to execute the path computation function between
the starting and ending sites in the Telecommunications Network Inventory application. You can
use this function for the path computation when you process the network inventory design and
assign.
You can use the Path Search function to identify the possible paths between your network sites.

If no path is found, the Path Search function uses the available input to create a logical connection without adding any connection elements. If you don't enter the end equipment, it selects any equipment that matches the Type
attribute that belongs to the end site. The function uses the start and end interfaces in the input to set the Port A and Port Z of the logical connections. Otherwise, it selects any interface in the Availability field, which is
marked as Available.

You can use this function as a Workflow Studio action in the Telecommunications Network Inventory workflow.

## Roles and availability {#path-compute-action__section_kfd_fdk_x5b}

Users with the admin role can add an action to a flow and define the configuration details of
the flow. This function is available as a Workflow Studio action in the Telecommunications Network Inventory application so that you can perform inventory-related data
operations.

## Input fields {#path-compute-action__section_klp_yzq_x5b}

The following table lists the input fields in the Path Search function and their description.
{#path-compute-action__table_w3g_2fm_1vb__entry__3}

| Name | Description | Data Type |
|-|-|-|
| Start Site | sys_id of the starting network site where this connection is configured. | String |
| End Site | sys_id of the ending network site where this connection is configured. | String |
| Start Equipment | sys_id of the starting network equipment where this connection is configured. | String |
| End Equipment | sys_id of the ending network equipment where this connection is configured. | String |
| Start Interface | sys_id of the starting network interface where this connection is configured. Note: If this field is left empty, it automatically selects the interface by using the path computation to create a logical connection. | String |
| End Interface | sys_id of the ending network interface where this connection is configured. Note: If this field is left empty, it automatically selects the interface by using the path computation to create a logical connection. | String |
| End Equipment Type | sys_id of the ending network equipment type where this connection is configured. | String |
| Logical Connection Model | sys_id of the logical connection model where this connection is configured. | String |
| Bandwidth | sys_id of the bandwidth of the connection. | String |
| Allowed Logical Connection Model | sys_id of the supported models for the logical connection. Click the add icon (![Add icon.]()) to add a logical connection model. | Array.String |
| Allowed Physical Connection Model | sys_id of the supported models for the physical connection. Click the add icon (![Add icon.]()) to add a physical connection model. | Array.String |
| Fail Action | Option to select the action when the function fails. You can select an action from the list. By default, the Create logical connection without path elements is selected. | Choice |
