VERY EASY USE OO ALV

AND TAKE HELP OF

Changing Field Catalog or Layout after First Display

During runtime, it is possible to set a new layout or a new field catalog after first displaying of the list. These components have set/get methods to accomplish this.

For the field catalog : get_frontend_fieldcatalog

set_frontend_fieldcatalog

For the layout : get_frontend_layout

set_frontend_layout
