How to enable additional fields in ALV- Verify Data Flow App

Hello,

Using the Verify Data Flow App, the layout in ALV has limited fields and doesn't show up in change layout setting too(eg. LC Amounts). I can go into each record, in the detailed screen section and then the fields show up. However this is for a single record only and does not help with report view of multiple lines. Is there a way to enable additional fields in the main ALV screen itself? Thanks in advance.

Regards,

Pooja
