# Locations - Sub Locations

<p class="callout info">The Sub Locations feature allows administrators to define more granular areas within a main system location, primarily for detailed incident reporting. Its primary purpose is to enhance the precision of incident documentation by pinpointing specific spots within a larger location, providing richer context for investigations and analysis. This article is intended for OPS-COM administrators responsible for managing geographic data and incident configurations.</p>

## Setup and Configuration

This feature is an administrative tool used to establish specific areas within your predefined physical locations.

**Admin Side:** Administrators must have the appropriate system role permissions enabled to access the location configuration menus and manage the geographic lists. Ensure your primary locations are already configured before adding sub-locations. Detailed instructions can be found on the *[Locations](https://opscom.wiki/books/setup-configuration-for-admins/page/locations "Locations")* page.

## Using this Feature

Administrators can use the following instructions to navigate the management interface to seamlessly add, edit, or delete various sub-locations.

### Accessing the Management Interface

1. Hover over **System Configuration**, click **Manage Locations**, then **Manage Sub-Locations**.

### Adding Sub Locations

1. Click the **Add Sub-Location** button.
2. Enter the name of your new sub-location in the provided text field.
3. Enter a geographic location code in the **GIS Number** field if your organization utilizes GIS maps.
4. Click the **Save Changes** button to create the new sub-location and refresh the list.

<p class="callout info">The GIS Number field is strictly optional and is only required for clients who utilize an external geographic location code system or mapping integration.</p>

### Editing Sub Locations

1. Locate the specific sub-location you wish to modify in the active list.
2. Click the **Edit** button next to the entry.
3. Make the necessary updates to the name or GIS number.
4. Click the **Save Changes** button to apply your updates.

### Deleting Sub Locations

1. Locate the eligible sub-location you wish to remove from the list.
2. Click the **Delete** button next to the entry.
3. Confirm the action to permanently remove the sub-location from the system.

<p class="callout warning">A sub-location can only be deleted from the system if it is not associated with any existing records. Administrators must first ensure that the sub-location is not actively referenced by incidents, violations, or other system data. Reassigning records to another valid sub-location is crucial to prevent data inconsistencies. If a sub-location is currently in use, the **Delete** button will not be available.</p>

## <span style="color: rgb(22, 145, 121);">Best Practices and Considerations</span>

- <span style="color: rgb(22, 145, 121);">**Add detail for incident reporting:** **Leverage sub-locations to provide specific detail that goes beyond the general location.** For example, within a main location like "Mulloy Library," you might create sub-locations for "Reading Room," "South Entrance," and "Loading Dock" to pinpoint exactly where an incident occurred.</span>
- <span style="color: rgb(22, 145, 121);">**Maintain clarity in naming:** **Use clear and concise names for your sub-locations.** Descriptive naming ensures incident reports are easily understandable for all administrators and enforcement officers reviewing the data.</span>
- <span style="color: rgb(22, 145, 121);">**Ensure accurate GIS integration:** **If your organization uses GIS data, ensure your GIS numbers for sub-locations are accurate and consistent with your mapping systems.** Mismatched codes can cause mapping errors or data syncing issues.</span>
- <span style="color: rgb(22, 145, 121);">**Verify data integrity before deletion:** **Always ensure that a sub-location is not actively referenced by any system records before attempting to delete it.** Attempting to force the deletion of an active sub-location can cause critical data conflicts with past incident reports.</span>
