# Transform settings

Configure the transform settings for your Integration Hub - Import integration. Specify batch size and empty-field handling, enable verbose mode, or run a script before or after the integration.

## Configure transform settings

You can configure the transform settings for your integration by selecting the **Transform Settings** button at the top of the Map to target page in Integration Hub - Import.

**Note:** The **Transform Settings** button doesn't appear until you've added at least one target table to the Map to target page. For more information, see [Map source data to a target table](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/integrate-applications/integration-hub/map-source-data-target.md).

Execute OnBefore Script

Option to run a script before inserting or updating data. Send notifications, modify data, or perform other actions before the integration begins.

 The onBefore script has three parameters.

-   **source**: The source data from the import record.
-   **target**: The transformed data from the import record. In the onBefore script, this parameter accesses transformed data before it's inserted into the target table.
-   **importLog**: The log that records information about data import activity.

 The onBefore script has two variables.

-   **ignore**. Type: Boolean. When **true**, the specified import set row is ignored.
-   **ignore\_reason**. Type: String. Message describing why the import set row was ignored.

</td></tr><tr><td>

Execute OnAfter Script

</td><td>

Option to run a script after inserting or updating data. Send notifications, calculate summaries, or perform other actions after the integration completes.

 The onAfter script has three parameters.

-   **source**: The source data from the import record.
-   **target**: The transformed data from the import record. In the onAfter script, this parameter accesses transformed data after it's inserted into the target table. Once a record is inserted or updated, it has a sys\_id.
-   **importLog**: The log that records information about data import activity.
