This ensures that when developers add more tables, they are automatically linked to the appropriate subscription, helping to track usage and prevent running out of entitlements. Show full answer Show less ## Key Features * **Mapping Custom Applications:** Link custom applications to product subscriptions for automatic updates when new tables are added. * **Tracking Custom Table Usage:** Monitor the usage of custom tables to ensure compliance with subscription entitlements. * **Renewal Maintenance:** Document current mappings before subscription renewals to retain custom table links, especially when new SKUs may be introduced. * **Custom Table Definition:** Custom tables are those created on the ServiceNow AI Platform, and their entitlements vary with the subscription type. * **App Engine Management:** For organizations using App Engine, manage custom applications and tables through Subscription Management, with different monitoring approaches for App Engine V1 and V2 subscriptions. ## Key Outcomes By maintaining accurate mappings of custom tables and applications to product subscriptions, organizations can ensure compliance, manage entitlements effectively, and avoid discrepancies during subscription renewals. It is essential to map any unmapped custom applications and tables promptly to keep entitlements updated and remain within compliance guidelines. Special considerations apply to grandfathered and exempted tables, which should be referenced in the organization's ServiceNow contract. Keep your custom table entitlements updated by mapping all of your custom applications and tables to valid subscriptions in Subscription Management. ## Overview of managing custom tables and applications {#allocating-custom-tables-subscr-apps-v2__section_ofz_qy4_5fb} To successfully manage your custom tables and applications, follow the process in this infographic. Figure 1. Managing custom tables and applications * [Map a custom application to a product subscription in Subscription Management](https://www.servicenow.com/docs/BV8XhrGIupXx05tRXG4szg "Maintain accurate entitlement for custom tables in a scoped application by mapping the application to a product subscription in Subscription Management. To stay in compliance, you must map custom tables to a product subscription.") Map a custom application to a product subscription so that when developers add more tables to the application, they're automatically mapped to the subscription. Track your custom table usage to ensure that your organization doesn't run out of custom table entitlements. * [Map custom tables to a product subscription in Subscription Management](https://www.servicenow.com/docs/fcmo93TwnuYJfJlKMcUh8g "Maintain accurate entitlement for custom tables in the global scope and stay in compliance by mapping the tables to a product subscription in Subscription Management. Mapping your custom tables keeps your custom table allotment updated and helps you avoid running out of custom table entitlements.") Map custom applications and custom tables on your production instance to a valid subscription. On non-production instances, mapping is recommended but not required. * [Maintain custom table and application mappings at renewal in Subscription Management](https://www.servicenow.com/docs/bBFkT3P9khBdy4G94Q5OYw "Ensure custom table and application mappings remain consistent throughout the renewal process.") When a subscription renews, a new product SKU might be added to your account. Maintain your current custom table mappings during the renewal process by documenting your mappings before the renewal date. {#allocating-custom-tables-subscr-apps-v2__ul_bxn_vy2_3yb} ## Custom tables {#allocating-custom-tables-subscr-apps-v2__section_mnc_j1d_yfb} A custom table is defined as a table that you create on the ServiceNow AI Platform that isn't provided by ServiceNow. Some tables are exempted from being classified as a custom table. Note: For more information on custom tables on the ServiceNow AI Platform, see [Table administration](https://www.servicenow.com/docs/YmfPYHQNDwErMUNh0RA6~A "A table is a collection of records in the database. Each record corresponds to a row in a table, and each field on a record corresponds to a column on that table."). For a detailed description of custom table use rights and exempt tables, see the Custom Table Guide on Subscriptions come with custom table entitlements that dictate the number of custom tables that you can map to a subscription. The number of custom table entitlements depends on the subscription. ## Custom applications {#allocating-custom-tables-subscr-apps-v2__section_vvl_dqb_3nb} A custom application is defined as an application that you create on the ServiceNow AI Platform that isn't provided by ServiceNow. If your organization purchased App Engine, you can use Subscription Management to manage your custom application subscriptions. ## App Engine usage {#allocating-custom-tables-subscr-apps-v2__section_uvy_fmp_4bc} App Engine subscriptions entitle you to develop applications and deploy custom tables in production instances. Based on your App Engine version, you monitor the subscription usage of your App Engine applications differently. * You can view and manage App Engine V2 subscriptions in Subscription Management just like any other product subscription. You can map your applications and custom tables to an App Engine V2 subscription and allocate per-user subscriptions by adding groups with measured roles to an App Engine V2 subscription. * You can't view App Engine V1 subscription details on the details page like other subscriptions. Users with the usage_admin, sn_sub_man.admin, or admin roles can view App Engine V1 subscription details and usage information by navigating to the App Engine usage module from the filter navigator. This module only appears if you have App Engine V1. For details on auditing App Engine V1 usage, see [KB0999383](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0999383). {#allocating-custom-tables-subscr-apps-v2__ul_x5q_jmp_4bc} * **[Map a custom application to a product subscription in Subscription Management](https://www.servicenow.com/docs/BV8XhrGIupXx05tRXG4szg)** Maintain accurate entitlement for custom tables in a scoped application by mapping the application to a product subscription in Subscription Management.
