By default, domain separation adds a domain field to the Task [task] and Configuration
Item [cmdb_ci] tables and their extensions.
You can also extend domain separation to any new tables you create by adding a
sys_domain field to the table's dictionary definition. By default, the
system only domain separates platform and baseline application tables where appropriate.
Warning: ServiceNow does not
recommend domain separating platform tables (any table with the sys_ prefix such as the
Dictionary Entry [sys_dictionary] and Dictionary Entry Override [sys_dictionary_override] tables)
because it can produce unexpected results.
The value of the sys_domain
field contains the domain assigned to the
record by any of the following:
- Company to which the user belongs
- Business rule when creating record
- Module used when creating record
- Form template used when creating record
- Domain of the parent record
- Domain assigned to User record
- Domain of the user who creates it
Domain separation restrictions:
The system prevents the following tables from being domain separated:
- Access Control
- Script Include
- System Property
- Security Black/Whitelist Entities
- Dictionary Entry
- Dictionary Entry Override
Administrators can quickly assign users to a domain by assigning them to a company. After users
are assigned to a domain, records automatically inherit the user's domain.
Administrators can automatically assign users to domains:
- Based on a company record
- Based on a default domain
For example, assigning Bow Ruggeri to the ACME company automatically assigns him to the ACME
domain. Assigning Don Goodliffe to the Initech company automatically assigns him to the Initech
domain. Any records they create are automatically added to the appropriate domain.
Administrators can use a business rule to automatically set a domain value when creating a
record. The business rule must set a value in the sys_domain field.
Administrators must ensure there is a sys_domain column available for the
Administrators can use the sysparm_domain URL parameter to automatically
assign new records to a particular domain from a module. Administrators must create a module with
an Argument value of:
Administrators can use a form template to automatically assign new records to a particular
domain. Administrators must add the sys_domain field to the form and
select a domain value. For example, setting the sys_domain field to
TOP/ACME domain automatically assigns all records from this template to
the TOP/ACME domain.
By default, related records inherit the domain of the parent record. For example:
- A change task record inherits the domain of the parent change request record.
- A problem record inherits the domain of the parent incident record.
If no other domain conditions apply, a record automatically inherits the domain of the user who
