# Excluded tables

You can't replicate certain tables in Instance Data Replication (IDR). Child tables of tables in the exclusion list are also excluded.

## Excluded tables {#IDR-excluded-tables__section_xnm_t3m_ycb}

These tables are excluded from IDR:

* Tables with the prefixes V_PREFIX, SYSX_, sys, ts_, ua_, usageanalytics_, wf_, ecc_, clone_, jrobin_, rrd_, imp_, pf_, pfd_, idr_sys_domain is an exception.

* Rotated tables, including syslog, sys_querystat, ecc_queue, ecc_event, cmdb_metric, sysevent
* Tables without a sys_id
* sso_federation
* saml2_update1_properties
* sso_properties
* digest_properties
* Instance

{#IDR-excluded-tables__ul_jb5_xgx_xfb}

Child tables that extend these tables are also excluded from IDR and should not be included in replication sets because replication fails if they are included. For example, sc_cat_item extends sys_metadata, which is an excluded table. This makes
sc_cat_item an excluded table due to inheritance.

Tables to avoid replicating:

* cmdb
* cmdb_ci

{#IDR-excluded-tables__ul_tc3_1n2_5vb}

If you determine the CMDB tables must be replicated, you must use conditions to constrain the count of replicated records and ensure all required columns are included in the replication set.
