- WDDOINIT method code
method wddoinit . wd_this->get_data( ). endmethod.
METHOD get_data .
DATA lo_nd_pa0002 TYPE REF TO if_wd_context_node.
DATA lt_pa0002 TYPE wd_this->elements_pa0002.
"Navigate from <CONTEXT> to <PA0002> via lead selection
lo_nd_pa0002 = wd_context->get_child_node( name = wd_this->wdctx_pa0002 ).
SELECT *
FROM pa0002
INTO CORRESPONDING FIELDS OF TABLE lt_pa0002
UP TO 40 ROWS.
lo_nd_pa0002->bind_table( new_items = lt_pa0002 set_initial_elements = abap_true ).
ENDMETHOD.
