# Create or modify a connection using the map editor

Use the map editor to add a relationship between two CIs or to modify an existing relationship.

## Before you begin

Role required: sn\_cmdb\_admin or sn\_cmdb\_editor

## About this task

-   A solid line indicates a relationship. The arrowhead indicates the dependent node.
-   A dashed line indicates a reference.
-   A badge on a line indicates the number of relationships between the CIs.

Two CIs might be connected by one or more relationships \(stored in the CI Relationship \[cmdb\_rel\_ci\] table\). For example, two CIs might be connected by the **Runs On::Runs**, **Depends On::Discovered From**, and by the **Owned By::Owns** relationships.

You can learn more about relationships at [CI relationships in the CMDB](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/configuration-management-database-cmdb/c_CIRelationships.md).

The map editor does not support the following actions:

-   Editing mapped application services \(service instances\).
-   Deleting reference or endpoint connections or removing from the map a CI that has reference or endpoint connections.
-   Updating the applicative flow relationship type \(connection between endpoint CIs\).

**Note:** At any time, select the reset icon \[Omitted image "icon-um-reset-map.png"\] to undo all unsaved changes.

## Procedure

1.  While editing a map, specify whether to create or modify a connection.
