Hello expert,

I am facing problem in display of the internal table's row data returned from read_text function module on web dynpro view in the text view UI element.

  is there any other  option than looping the internal table and geting the data into string .

Hi vishal,

Use belo code to get data into string...

Use below code to get text..

->Create text object in SO10

->Do coding like below...

     data:      lt_tline type table of tline,

               ls_tline type tline,

                lv_string type string.

1. use 'READ_TEXT' FM to get text from SO10 which give you TLINE format table (lt_tline).

loop at lt_tline into ls_tline.

      concatenate lv_string ls_tline-tdline into lv_string.

      clear: ls_tline.

endloop.

2. Now lv_string contains full text of SO10.

            3. Bind lv_string to textedit UI element text.

Thanks for reply but I dont want it to do using loop at  lt_line. because i want to display as formated string where all new lines also should come.

Hi Vishal,

To preserve newlines from the standard text object in the TextView string you need to loop through the text lines returned by READ_TEXT and pay attention to the TDFORMAT of each line. Try the following.

* -- Read text

  CALL FUNCTION 'READ_TEXT'
    EXPORTING
      id       = ls_thead-tdid
      language = ls_thead-tdspras
      name     = ls_thead-tdname
      object   = ls_thead-tdobject
    TABLES
      lines    = lt_lines
    EXCEPTIONS
      OTHERS   = 0.

* -- Construct the text string

  LOOP AT lt_lines ASSIGNING <t> WHERE tdformat <> '/*'. " not a comment
    CASE <t>-tdformat.
      WHEN '*'. " is a newline
        CONCATENATE text_string
                    <t>-tdline
                    INTO text_string
                    SEPARATED BY cl_abap_char_utilities=>cr_lf.
      WHEN OTHERS.
        CONCATENATE text_string
                    <t>-tdline
                    INTO text_string
                    SEPARATED BY space.
    ENDCASE.
  ENDLOOP.

Cheers,
