I have a lcl_application class with its implementation. The only method defined is 'handle_node_double_click'. I want to display some fields in a dynpro when double click on one button and I want also to disable these fields when some others are pushed.
In fact, into the CLASS lcl_application IMPLEMENTATION I can not use 'loop at screen. if screen-name='ZT'. screen-input = '0'. endif. modify screen. endloop'. It does not work.
How can I do it ??
Thanks.
