Background documentation Explanation UI Element  Locate the document in its SAP Library structure

You can use the UI element Explanation on your views for explanatory texts. The UI element explanation contains a text that appears on the screen permanently and should contain explanations about the screen or parts of the screen.

In the View Designer you can create the text for an explanation of the text property. The text can either be entered manually (a maximum of 255 characters) or it can be an OTR alias text, for which you use the notation $OTR:Aliasname. You can also write a script that allows for texts longer than 255 characters and of various formats. To do this use method WDDOMODIFYVIEW.

Example

method wddomodifyview.

  data lines              type tlinetab.
  data header             type thead.
  data text               type string.
  data wad_formatted_text type ref to cl_wd_formatted_text.
  data ui_explanation     type ref to cl_wd_explanation.

  call function 'DOCU_GET'
    exporting
      id                = 'TX'
      langu             = sy-langu
      object            = 'WDR_TEST_HELP_EXP1'
    importing
      head              = header
    tables
      line              = lines
    exceptions
      no_docu_on_screen = 1
      no_docu_self_def  = 2
      no_docu_temp      = 3
      ret_code          = 4
      others            = 5.
  if sy-subrc <> 0.
    text = space.
  endif.

  wad_formatted_text = cl_wd_formatted_text=>create_from_sapscript( sapscript_head  = header
                                                                    sapscript_lines = lines
                                                                    type            = cl_wd_formatted_text=>e_type-wad
                                                                  ).
  if wad_formatted_text is bound.
    text = wad_formatted_text->m_xml_text.
  else.
    text = ''.
  endif.

  ui_explanation ?= view->get_element( 'ON_SCREEN_EXPL1' ).
  ui_explanation->set_text( text ).

  wd_this->m_view = view.

endmethod.

The text of an explanation is highlighted differently to other UI texts when the design emphasized is selected, since in addition to the text being underlined in blue, the switch Hide Quick Help is also displayed.

The option for More Field Help in the context menu is used to display technical information as well as the full data element documentation, if the field on which it was called, is linked to the ABAP. If it is not, only the technical information is displayed. See Classic F1 Help.
