Hi Lakshmi,
Create an action for the onselect event. and implement the following logic
data: lo_nd_ddix type ref to if_wd_context_node,
lo_el_ddix type ref to if_wd_context_element,
ls_ddix type wd_this->element_ddix.
lo_nd_ddix = wd_context->get_child_node( 'DDIX' ).
lo_el_ddix = wdevent->get_context_element( 'CONTEXT_ELEMENT' ).
lo_el_ddix->get_attribute( exporting name 'ATTRIBUTE' importing value = lv_ddix ).
or
lo_el_ddix->get_static_attributes( importing static_attributes = ls_ddix ).
Hope this should help you.
Thanks & Regards,
Sankar Gelivi
