Setting up domain separation involves requesting activation of a plugin, setting
options, and assigning users and records to domains.  
Do the following to set up domain separation:

1. [Request domain separation](https://www.servicenow.com/docs/de_7ezFo_xfmGY89kUFsIw "All domain support features are activated with a plugin called Domain Support - Domain Extensions Installer. Administrators can request activation of this plugin.")
2. [Create a domain](https://www.servicenow.com/docs/5sZqeiRfCkQ1ppmybdJq3g "You can create a domain by creating a record in the [domain] table.")
3. [Add a domain field to a table](https://www.servicenow.com/docs/vs9zOTFqF96kgB5JCR_YcA "As an administrator, domain-separate a custom table by adding a sys_domain field to it.")
{#c_DomainSeparationSetup__ol_jqj_4tf_l1b}  
You can also perform these basic administrative tasks on domains:

* [Enable or disable a domain](https://www.servicenow.com/docs/X1BAIU38LFlUyJdOzuIkCg "When you activate or deactivate a domain, the activation status cascades to companies within the domain.")
* [View domain relationships](https://www.servicenow.com/docs/63jzIQ_RN3YyzJc4RMheFQ "The domain map offers domain administrators a read-only representation of the active domains on the instance and how they relate to each other.")
* [Expand domain scope](https://www.servicenow.com/docs/F1rZ8J5lG41O~XRJqWxslA "By default, when a user in the global domain views a table containing a sys_overrides column, the user sees records from only the global domain. When an admin in the global domain views a process table, that admin sees only records that are in that process table.")
* [Create a domain-specific choice list](https://www.servicenow.com/docs/JDBBxQ6dF2BmgBsMqDckxg "Administrators can configure choice lists to contain entries specific to a particular domain.")

See [Advanced domain separation administration](https://www.servicenow.com/docs/bMq7HiW58Hr8xJtbs0n~xQ "Administrators can view information about domain separation, identify potential issues, and change configuration settings.") for a list of tasks to perform after
you set up domain separation and perform basic administration.
