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

## Before you begin

Role required: admin

## About this task

For example, you create a new custom table, named
<kbd class="ph userinput">transactions</kbd>, that stores transactional information and
contains an FX Currency field called <kbd class="ph userinput">cost</kbd>.

## 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://www.servicenow.com/docs/tOKgsEGCrTBofaxk4~vS6w "Administrators and application developers can create custom tables to store application data. After you create a table, you can also modify field types and field labels.").
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, <kbd class="ph userinput">cost</kbd>.
4. In the Type field, select FX Currency as the field type.  
5. As needed, enter other required parameters.  
   Note:  
   Do not change the Max length value for FX Currency in custom tables. Max length must be 32 (default).
6. Click Submit.
