# Add or modify a transaction cancellation message

The Quota Manager uses a UI page to control the contents of the transaction cancellation message.

## Before you begin

Role required: admin

## About this task

Knowledge of [Apache Jelly](http://commons.apache.org/jelly/) is highly recommended when modifying the UI page. See [Extensions to Jelly syntax](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/api-reference/scripts/c_ExtensionsToJellySyntax.md) for more information.

## Procedure

1.  Navigate to **All** > **System UI** > **UI Pages**.

2.  Open the UI page with the name **transaction\_canceled\_quota**.

3.  In the **HTML** field, add or modify the new cancellation message.

    To add variable information to the cancellation message, see [Methods to add variable information to the cancellation message](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/platform-performance/r_AddVarInfoToTheCancellationMsg.md).

4.  Click **Update**.
