# Create an Order or OrderItem Field Set

To update any fields other than the fields in the preceding list, you can create a field set on Orders for Order field updates and OrderProducts for OrderItem field updates. The fieldset name and label should match CartAllowedFieldSet for both Orders and OrderProducts.

To create a new field set:

1.  Navigate to **Setup** then select either **Orders** or **OrderProducts**, then select **Field Sets**.

2.  Add a new fieldset with name and label. For this example, we will use: `CartAllowedFieldSet`

3.  Any customer created custom fields are allowed by SF Field Data security, when it is part of CartAllowedFieldSet Field Set. In this example, we are adding `Order Start Date`.

4.  Verify the new custom field is present:

    1.  Use the Create Cart API to create a new basket and save the CartContextKey.

    2.  Call the Create Cart API again using the CartContextKey and the new fieldset as shown using REST Explorer below:
