If you have an assigned role of currency_instance_admin, you can review and edit the details of a currency entry in an FX Currency field. You can't edit the reference currency and value because they are calculated
automatically.

## Before you begin

Role required: admin, currency_instance_admin, with ACL access to the FX Currency field.

## Procedure

1. Access the Currency Instance record using one of the following methods.

   | Access method | Description |
   | Direct access from an FX Currency field | Click the edit icon (![Edit icon]()) that appears next to the FX Currency field in a transaction record. |
   | From the navigator bar | 1. Navigate to System LocalizationFX Currency Configuration. 2. Click the Currency Instance record to edit. {#updating-fx-currency-instance-record__ol_nb1_5cw_5jb} Note: Only users with an assigned admin role can access this selection from the navigator. |

   | Field | Description |
   |-|-|
   | Amount | Currency amount that you entered into the FX Currency field, formatted according to the currency code in your user locale. The amount stores internally as a currency code and a numerical value of up to 12 digits in length. For example, `USD; 1234.56`. Note: The currency value has two parts: the currency amount and a currency code. The amount stores as a decimal value, for example, `1234.56`. |
   | Currency Code | Three-letter ISO code that identifies the currency that you select for the currency amount. For example, USD for the US Dollar, or EUR for the Euro. |
   | Conversion Rate | Conversion rate used to calculate the reference currency value. It converts a session currency value, expressed in one currency, to another, and stores as a reference to a record in the Currency Conversion Rate \[fx_conversion_rate\] table. The conversation rate is based on the Conversion Rate Table and Conversion Date Source settings for the FX Currency field in the Rate tab of FX Currency Configuration. To learn more about these settings, see [Configuring FX Currency field behavior](https://servicenow-prod.fluidtopics.net/qK7lN0TKzVNY9eYTRS1nHA "After establishing global currency defaults, you can create custom FX Currency configurations for specific table fields. Identify the table fields that use FX Currency, and define how currency conversion calculations should be performed, displayed, filtered, and aggregated."). You change or select the conversion rate as needed. |
   | Reference Amount | Calculated reference currency amount. The ServiceNow AI Platform converts the currency value entered into the Amount field into a common reference currency. It uses the settings in the Reference Currency Source and Reference Currency fields in System LocalizationFX Currency Configuration to do so. You can't change the calculated reference amount. Note: To learn more about reference currencies, see [Set the reference currency](https://servicenow-prod.fluidtopics.net/1Gkrcd4pUUheSu4UciKYdQ "Set the reference currency for the designated FX Currency field. The ServiceNow AI Platform uses the reference currency to convert values entered into the FX Currency field into a common currency for report aggregation purposes."). |
   | Reference Currency Code | Three-letter ISO code that identifies the reference currency, for example, USD, to which the entered currency value converted. You can't change the reference currency code. |
