Hi Dominic,
It depends on your layout requirement(Please go through Usage and significance of various layouts in WebDynpro Abap to understand all the layouts and their significance and pick the best one).
To move an element to right side from left end you may also use 'invisible element' UI element. To achieve this, you will have to take a transparent container with matrix layout(you may choose your own) and have an invisible element before the view container (which contains ALV view). Also, set the width of invisible element
I could get the output as below->
Let me know if this helps.
Thanks & Regards
Mohit
