    Hi, I managed to access the context node of a component usage in one of my projects with the code below.

    Unsure if this is the best way of doing it, but it seems to work.

    data lr_window type ref to cl_bsp_wd_controller.

    data lr_comp_controller type ref to <<COMPONENT CONTROLLER CLASS FROM YOUR COMPONENT USAGE>.

    "--- Get the interfaced window from your component usage...

    lr_window ?= me->get_subcontroller_by_viewname( iv_viewname = 'CU_YOUR_COMPONENT_USAGE.USED_COMPONENT/MainWindow' ).

    check lr_window is bound.

    "--- Get component controller from component usage

    lr_comp_controller ?= lr_window->m_parent.

    "--- Check component usage context node size...

    check lr_comp_controller->typed_context->parent->collection_wrapper->size( ) > 0.

    "--- Get something out of the context node...

    data(lv_id) = me->typed_context->your_context_node->collection_wrapper->get_current( )->get_property_as_string( iv_attr_name= 'ID' )
