Based on Certain conditions you can set the NO_OUT = 'X' or SPACE in fieldcatalog for the fields which you want them to see or not in LIST...

if some condition....

x_fieldcat-...

x_fieldcat-..

x_fieldcat-no_out = 'X'.

endif.

if some condition....

x_fieldcat-...

x_fieldcat-..

x_fieldcat-no_out = ' '.

endif.

Savita,

Please check my blog.

/people/ravikumar.allampallam/blog/2005/05/31/expand-the-list-of-columns-in-a-report-dynamically

This should give you an idea. If you have further questions please let me know.

Setting NO_OUT flag is not the right solution because if the user tries to change the layout entire list of fields will be available for him.

Ravi
