ALV Freeze clumn header and TOP OF LIST alignement issue

Hi All,

I am facing two issues in WEbdynpro ALV,

1. I wanted to freeze the ALV column headings while scrolling down. I have used SET_FOOTER_VISIBLE , but there is no difference.

2. I wanted add header with selection screen details. I am able to add fields in the header using TOP OF LIST. But Label and text are not aligned properly. THere is lot of space between Label and text. How can I align it properly ?

Thanks,

Varughese V John
