This feature is crucial for maintaining governance and standardization within multi-tenant environments. Show full answer Show less Table Builder facilitates the configuration of form layouts and logic for tables within these domains. It is designed to work with domain separation when launched from UI Builder, but not from App Engine Studio. ## Key Features * **Domain Overrides:** Developers can switch the session domain to create overrides for form layout, section layout, and form logic. * **Standardization:** Ensures a consistent configuration across instances, helping to minimize code sprawl and enhancing the adoption of new features. * **Visibility:** In the global domain, developers can view all form views across different domains, with overrides indicated by specific icons. * **Governance:** Effective management of multiple domains is essential, as it helps maintain a stable and scalable ServiceNow instance. ## Key Outcomes With domain separation and Table Builder, ServiceNow customers can efficiently manage diverse business logic across multiple tenants while ensuring a uniform user experience. This capability supports the configuration of necessary domain-specific changes when required, allowing for flexibility without compromising overall system integrity. As a result, organizations can better govern their instances and streamline operations in a multi-tenant environment. Domain separation enables you to separate data, processes, and administrative tasks into logical groupings called domains. You can control several aspects of this separation, including which users can see and access data. ## Support level: Standard\* {#form-builder-domain-separation__section_azq_vzk_lsb} The support level is Standard but has some exceptions or special conditions.{#form-builder-domain-separation__p_usc_nfg_h1c} * Includes all aspects of Basic level support. * Business logic: The service provider (SP) creates or modifies processes per customer. The use cases reflect proper use of the application by multiple SP customers in a single instance. * The instance owner must be able to configure minimum viable product (MVP) business logic and data parameters. This configuration is done per tenant, as expected for the specific application. {#form-builder-domain-separation__ul_fgh_3dx_zkb} Sample use case: An admin must be able to make comments required when a record closes for one tenant, but not for another.{#form-builder-domain-separation__p_vsc_nfg_h1c} For more information on support levels, see [Application support for domain separation](https://www.servicenow.com/docs/access?context=domain-separated-apps&version=australia&pubname=australia-platform-security&ft:locale=en-US).{#form-builder-domain-separation__p_wsc_nfg_h1c} ## Overview of domain separation {#form-builder-domain-separation__section_ets_21l_lsb} Table Builder enables developers to configure the layout and logic for each form view for tables in their application. When launched from UI Builder, Table Builder supports domain separation, which is the ServiceNow instance-wide multi-tenant architecture. Note: Domain separation is supported for Table Builder when it is launched from UI Builder. Domain separation is not supported when launching Table Builder from App Engine Studio. Table Builder enables developers in domain-separated environments to create forms while they are in the same browser window. Domain separation in Table Builder works similarly to an application scope that helps administrators to create or edit in a multi-tenant environment. Standardization is the key principle to maintaining a stable, healthy, and scalable ServiceNow instance, where domain separation is installed. By having standardization, you have a common configuration that most of the instance operates by. When an instance has hundreds or thousands of domains, managing them successfully requires rigorous governance. Domain-specific configurations should be done only if they are deemed necessary by the instance owners. Most instances should follow the common instance configuration to provide a more uniform experience across the instance. It also lets instance owners minimize the code sprawl that slows the adoption of new ServiceNow features that are included as part of the release upgrades. ## How domain separation works in Table Builder {#form-builder-domain-separation__section_fts_21l_lsb} Table Builder enables developers to switch the session domain to create domain overrides to the form layout, section layout, and form logic. System dictionary record changes (such as field metadata for a field label) do not require domain overrides. Form layout changes require domain overrides to both the form record and the section when the change is performed at a lower domain. When creating a domain override, section labels can't be edited prior to saving the override. Note: UI policies can have overrides at lower domains, as well. An override indicator appears on the UI policy. In the global domain, a developer can expand the domain scope to see all form views from different domains. Developers can see all form views and views with overrides that are indicated with an icon. Note: Single section form records do not have a sys_ui_forms record attached to it. Instead, these records only have an attached sys_ui_section record until a second section is created. If a single section form has existing domain overrides, and the developer adds another section to the form, the existing domain overrides will break. **Related topics** * [Domain separation for service providers](https://www.servicenow.com/docs/access?context=domain-sep-landing-page&version=australia&pubname=australia-platform-security&ft:locale=en-US)
