hi ,
follow these steps:
1. After you selecte the search help for New Responislbe person, domodify gets triggered.
2. In the wddomodify, get the value of New Responsible person by reading the attribute binded to it.
3. Now if Value entered is not initial, write a selecte query to fetch the name based on pernr no.
4. Finally bind the name fetched with the attribute binded to New Responsible person name.
Wdomodify :
************* *Read the New REsponsible person Pernr* ***********
  DATA lo_nd_cn_sflight TYPE REF TO if_wd_context_node.
  DATA lo_el_cn_sflight TYPE REF TO if_wd_context_element.
  DATA ls_cn_sflight TYPE wd_this->element_cn_sflight.
  DATA lv_carrid LIKE ls_cn_sflight-carrid.
* navigate from <CONTEXT> to <CN_SFLIGHT> via lead selection
  lo_nd_cn_sflight = wd_context->get_child_node( name = wd_this->wdctx_cn_sflight ).
* get element via lead selection
  lo_el_cn_sflight = lo_nd_cn_sflight->get_element(  ).
* get single attribute
  lo_el_cn_sflight->get_attribute(
    EXPORTING
      name =  `PERNR`
    IMPORTING
      value = lv_carrid ).
****** *Check whethre a value has been entered in PERNR* *************
if lv_carrid is not initial.
*************Select Name based on pernr entered* ***********
select ename from pa001 into lv_ename where pernr = lv_carrid.
*******Set the Name atttribute with the ename value fetched* *****
  lo_el_cn_sflight->set_attribute(
      name =  `NAME`
      value = lv_cename ).
endif.
