Some Netsuite form fields are not returned in API responses without adjusting settings manually in the Netsuite user interface. For instance, the
amountPaid fields are listed in Netsuite's definition of their invoice object, but are not returned unless enabled in the UI. Here are the steps to enable the
amountPaid fields for invoices:
1. Navigate to an existing invoice.
2. Hover over "Customize" in the top-right corner and click "Customize Form".
3. Click the "Screen Fields" tab.
4. For both the "Amount Paid" and "Amount Remaining" table entries, click the checkbox in the "Show" column.
5. Click "Save".
