Hello gurus,
I am creating one application and need your help. on my webdynpro screen I have few fields, out of these user will enter some and one field I want to populate when user hit enters. My application is to create a sales order, user will enter the details and hit create button that will create the sales order. Now what I want is when the sales order is created on the same screen the sales order number should also be displayed in the field : VBELN. Can you please tell me how can I get this.

Hi Rajeev, if I understand you want show in a field that was created the VBELN after execute BAPI, well I assume that this field is binding with context document->Att_VBELN. You can use the code below.
    DATA lo_nd_document TYPE REF TO if_wd_context_node.
    DATA lo_el_document TYPE REF TO if_wd_context_element.
    DATA ls_document TYPE wd_this->element_document.
    DATA lv_att_vbeln TYPE wd_this->element_document-att_vbeln.
    lo_nd_document = wd_context->get_child_node( name = wd_this->wdctx_document ).
    lo_el_document = lo_nd_document->get_element( ).
    IF lo_el_document IS INITIAL.
    ENDIF.
   lv_att_vbeln = <<RETURNED VBELN FROM BAPI>>.
    lo_el_document->set_attribute(
      name =  `ATT_VBELN`
      value = lv_att_vbeln ).
