# Add an FX Currency field to a table

Before using and configuring an FX Currency field, you first add it an existing table, or to a new one, in **System Definition** > **Tables.**

## Before you begin

Role required: admin

## About this task

For example, you create a new custom table, named `transactions`, that stores transactional information and contains an FX Currency field called `cost`.

## Procedure

1.  Follow the normal procedures to add a table, or access an existing table.

    To learn more about creating and modifying tables in an instance, see [Create a table](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/platform-administration/table-administration-and-data-management/t_CreateATable.md).

2.  In the **Columns** section, use the **Table Columns** embedded list to add columns to the table.

3.  In the **Column label** field, enter the column name.

    For example, `cost`.

4.  In the **Type** field, select **FX Currency** as the field type.
