NOTE: To be able to capture deleted records, your ServiceNow Service Account must have Read permission for the
sys_audit_deletetable in ServiceNow. The_fivetran_deletedcolumn will not appear in a destination table until Fivetran sees the first deleted record for that table in the ServiceNowsys_audit_deletetable.
IMPORTANT: You don't have to include the
sys_audit_deletetable for the capture deletes feature to work. Including this table only slows up the sync due to the large size of this table.
Setup guidelink
Follow our step-by-step ServiceNow setup guide to connect ServiceNow with your destination using Fivetran connectors.
Initial synclink
When a new account is first connected, Fivetran will sync every table present in the instance for which read permission was granted. We import each table in full before moving onto the next table. Depending on the number and size of tables to be imported, initial sync can take a while.
Schema informationlink
ServiceNow schema follows Fivetran's standard API schema rules.
Schemalink
Fivetran currently supports all tables as well as any custom tables present in your ServiceNow account and the schema diagrams illustrating how tables relate to one another.

ServiceNow uses the Class Table Inheritance pattern. Most of the tables are children/leafs of the Task or CMDB_CI table. Please join on the sys_id field of the child table to recover the complete record.
Updating datalink
Fivetran will use one of the following strategies to update the tables that you included in your sync:
Incrementallink
Tables which have a sys_updated_on or sys_created_on column are updated incrementally.
Reimportlink
Some tables do not have the necessary columns to be updated incrementally. They must be reimported in full to update. In order to speed up overall updates, the frequency with which we update these reimport tables is based on how fast we can ingest them from ServiceNow. This speed is entirely dependent on ServiceNow performance.
| Table Import Duration | Import Frequency |
|---|---|
| 3 seconds or less | Every sync |
| Between 3 seconds and 5 minutes | Twice a day |
| More than 5 minutes | Once a week |
Tables that take longer than 3 seconds to import get marked as not recommended on the dashboard and include a message on how frequently Fivetran will sync them. They will be excluded from the sync by default as they degrade performance. However, customers can choose to include them.
Excluded Tableslink
Fivetran cannot update a table which do not contain sys_id column using one of the strategies above and is excluded from the sync. They will be marked on the dashboard. Customers cannot optionally include them in the sync.
Syncing empty tables and columnslink
Fivetran can sync empty tables and columns for your ServiceNow connector. For more information, see our Features documentation.
Syncing reference typeslink
Query response for reference types reference, domain_id, and document_id contains values for "link" and "value". Fivetran adds these values to columns with _LINK and _VALUE postfixes.
Get display valuelink
Fivetran doesn't not support syncing of the display value for the reference types. You can obtain these values using the JOIN TABLES operation in your warehouse. You can find the reference table name in ServiceNow UI or as the _LINK column value following the /table/<table_name> format. Then, you can use the value from the _VALUE column to join the reference table on the sys_id column.
