How to add Change Layout Button to ALV Toolbar?

Hi All,

I am using a SAP GUI STATUS 'STANDARD' that has almost all the funcationality needed except for the change layout button.

I have tried changing the GUI STATUS to 'STANDARD_FULLSCREEN' which has the button I am looking for but it does not show up.

What am I missing to have the 'Change Layout' Button show on the toolbar?

thank you
