To extend a data-separated base table and ensure that the table extension is also data-separated, you must add the sys_domain, sys_overrides, and Domain Path fields. This ensures that the new table inherits the domain separation properties of the base table, maintaining data integrity and security across different domains.

* sys_domain: This field references the Domain table and is essential for domain separation.

* sys_overrides: This field is used to manage overrides in the domain-separated environment.

* Domain Path: This field helps in maintaining the hierarchical structure of domains.

In ServiceNow, even though the Inbound Actions table has a domain field, records in this table should all be placed in the Global domain. This is because inbound actions, such as inbound email actions, are designed to be accessible across the entire platform, regardless of the specific domain. By placing these records in the Global domain, ServiceNow ensures that the actions can be executed and managed universally, without domain-specific restrictions.

For example, if an inbound email action creates an incident, the system creates the incident in the same domain as the user in the Caller field. If that user is not in the User [sys_user] table, the incident is placed in the Global domain1.

This approach maintains the integrity and accessibility of inbound actions across the platform.

When handling process domains in ServiceNow, the recommended approach is to create overrides in the process domain rather than updating the global processes. This strategy ensures that any customizations or specific requirements for a particular domain do not interfere with the global processes, which are intended to be standard and consistent across the entire organization.

Creating overrides in the process domain allows for more granular control and flexibility, enabling specific adjustments without impacting the overall system's integrity. This approach aligns with best practices for maintaining system stability and ensuring that updates or changes are isolated to the relevant domain.

ServiceNow recommends a domain separation approach that maximizes the use of standard configurations while minimizing custom configurations. This approach ensures maintainability, scalability, and ease of upgrades. The recommended approach is:

* 80% or more Standard: Utilizing out-of-the-box (OOTB) configurations as much as possible to leverage ServiceNow's built-in capabilities and best practices.

* 15% or more data-driven: Using data-driven configurations to adapt to specific business needs without extensive custom coding.

* Less than 5% Configuration: Minimizing custom configurations to reduce complexity and potential issues during upgrades.

This strategy aligns with ServiceNow's best practices for domain separation, ensuring that the system remains robust and easier to manage.

To assign a user record to a specific domain other than the one based on their company, you should use the ''Managed Domain'' option and set their domain field to the desired domain. This method allows administrators to manually assign a user to a different domain, ensuring that the user has the appropriate access and permissions within that domain.

* ServiceNow Documentation on Domain Separation explains how to set the domain for a user.

* ServiceNow Developer Documentation provides detailed information on domain separation and managing domains.

Visibility in ServiceNow can be granted to users through Group Membership and Role.

* Group Membership: Users can be assigned to specific groups, and these groups can be granted visibility to certain records or functionalities within ServiceNow. This method allows for efficient management of user permissions based on their group affiliations.

* Role: Roles define a set of permissions that can be assigned to users. By assigning roles to users, administrators can control what users can see and do within the platform. Roles are a fundamental part of access control in ServiceNow.

Setting the Choice Action to ''Ignore'' on a transform field map in ServiceNow is used to avoid inserting dummy referenced records into the global domain. When importing data, if the system encounters a reference field value that does not match any existing records, setting the Choice Action to ''Ignore'' will prevent the creation of a new, potentially incorrect record. Instead, the system will skip the field and leave it blank, ensuring data integrity and avoiding the clutter of unnecessary records.

In ServiceNow, domain separation allows organizations to segregate data, processes, and administrative tasks into logical groupings called domains1. This is particularly useful for Managed Service Providers (MSPs), where multiple organizations or customers use the same ServiceNow instance but require isolation from each other2.

When a user has the ITIL role within the MSP domain, they inherently have that role across all domains they have access to. This is because roles in ServiceNow are global by default, meaning they apply across all domains unless specifically restricted31. The ITIL role is a set of permissions that typically includes the ability to manage incident, problem, and change records, which are fundamental to IT service management.

The other options, such as being granted the Admin role in other domains (B), administering other domains by granting the Domain Admin role , or being restricted to self-service in other domains by granting the Self-Service role (D), are actions that require explicit configuration by an administrator with the appropriate level of access and are not automatic outcomes of having the ITIL role in the MSP domain4.

It's important to note that while the ITIL role may be global, access to specific records and the ability to perform certain actions can still be controlled within each domain through ACLs (Access Control Lists) and other domain-specific configurations1.

In ServiceNow, domain visibility determines whether users from one domain can access records from another domain. To grant domain visibility to a user, you can:

AAssociate a visibility domain to one of the user's roles: This allows any user with that role to see records in the associated visibility domain1.

EAssociate a visibility domain to one of the user's groups: Groups grant their members the visibility domains of the group, which means when a user is part of a group, they inherit the visibility domains associated with that group1.

It's important to note that when a user leaves a group, they lose the group's visibility domains, and the use of visibility domains should be done thoughtfully as excessive use can slow performance2. Moreover, the domain hierarchy should be optimal to prevent performance issues2.

The options B, C, and D are not standard practices for granting domain visibility according to the ServiceNow documentation and best practices. Specifically, associating a visibility domain directly to a user record or setting the visibility domain's parent to the user's domain are not mentioned as recommended methods3421.
