# Delete a connection

# Delete a connection using the map editor {#ariaid-title1}

While editing a map, you can delete a connection (a relationship record) from the CMDB. The CIs that are involved in the connection are not deleted from the CMDB.

## Before you begin

Role required: sn_cmdb_admin or sn_cmdb_editor

## About this task

Warning:  
Deleting a connection might result in an invalid CMDB state.  
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).
{#unified-map-delete-connection__ul_u1z_mhd_v2c}

* When you delete a connection, the connection is removed from the map (hidden). The relationship is deleted from the \[cmdb_ci_rel\] table only when you save your changes.

* When you delete all connections between one CI and another CI so that no connection path remains to the home node, the isolated CI and all of its downstream connections are considered an island branch. When you save, changes that you made to downstream connections are saved and the island branch CI is removed from the map (hidden). The CI record is not, however, removed from the CMDB.{#unified-map-delete-connection__ph-um-island-ci}
* When you delete all connections to and from a CI and save the change, the following actions occur:
  * The records of all relationships --- both upstream to and downstream from --- the CI are deleted from the CMDB \[cmdb_ci_rel\] table.
  * The CI is removed from the map (hidden).
  * The record of the CI in the CMDB is not deleted.

You can learn more about relationships at [CI relationships in the CMDB](https://www.servicenow.com/docs/t8bRTxcodffEr1bSCD9L1g "The CMDB, in contrast to a static asset list, helps you track not only the configuration items (CIs) within your system, but also the relationships between those items.").
At any time, select the reset icon ![]() to undo all unsaved changes.

## Procedure

1. While editing a map, take one of the following actions:  
   Note:  
   No deletions happen until you select Save.
   * To delete a single connection, select it and then select Delete in the Attributes panel. Alternatively, right-click the connection and then select Delete.
   * To delete only particular connections for a CI, select the CI. In the editing panel, scroll to the connections and select Delete.
   * To delete all connections both upstream and downstream of a CI, select the CI and then select Remove CI.

2. Deletions happen when you select Save.
