# Sync a table vocabulary source

# Sync a table vocabulary source {#ariaid-title1}

Synchronize your table vocabulary sources to obtain the latest changes to the ServiceNow source table. Synchronizing your vocabulary sources ensures your NLU models have the latest values when predicting intents.

## Before you begin

* Make sure that the NLU Workbench plugin, NLU Workbench - Core plugin, NLU Common Model plugin, and Predictive Intelligence plugin are all installed and activated on your instance.
* Role required: admin or nlu_admin
{#sync-table-vocabulary-source__ul_shl_vvs_tgb}

## About this task

When you reference a vocabulary source in an utterance, it pulls the values at the time the model is trained. However, if the table values change over time, the model still references the values from the last training
session.

You can select a schedule to automatically refresh the vocabulary values used by NLU. This schedule can be edited later. For more information, see [Create a table vocabulary source](https://servicenow-prod.fluidtopics.net/f_YY3emeisk2eJFk_Eq3uw "Use the values from a ServiceNow table as a vocabulary source. Your Natural Language Understanding (NLU) models use your provided synonym to interpret utterances that contain values from the chosen source fields of the table.").

You can also manually sync a table vocabulary source, such as before model training.  
Note:  
If an utterance references a table vocabulary source that has never been synchronized, the model fails to train. Check the vocabulary source's current status, and sync manually if Never synced.

In the following example scenario, you're manually syncing the @AccessRoles vocabulary source to the Catalog Item table.

## Procedure

1. Navigate to AllNLU WorkbenchVocabulary Sources.
2. In the ServiceNow Tables tab, point just to the right of the Refresh column to invoke the Sync lookup icon.  
3. Select Sync.  
   The vocabulary source starts synchronization.

## What to do next

The syncing operation can take some time, depending on the source table size.

The values in the Last refresh and Current status columns reflect the current status of the vocabulary source.

Proceed to train your model. For more information on model training, see [Train and try your NLU model](https://servicenow-prod.fluidtopics.net/4XbdTt0aQvTMtxtl8ueabA "Train and try your model iteratively so that its intents and entities are validated, compiled, and saved to your model.").

Knowledge Base.
