IF_WD_CONTEXT_NODE interface methods withn ABAP Web Dynpro to enable users to view and change data
Here is a list of all the methods contained within the interface IF_WD_CONTEXT_NODE. This is the reference type for accessing the context elements associated with UI elements on your web dynpro application. This would be declared using abap code similar to the following and demonstrates how to use a few of the methods from the list below:
Data: context_node type ref to if_wd_context_node,
it_scarr type standard table of scarr.
select * from scarr into table it_scarr where CARRID = 'AA' .
context_node = wd_context->get_child_node( name = 'CARRIERS'). "CARRIERS' is the context node
context_node->bind_table( it_scarr ).
