You can read the text using READ_TEXT and put in a text editor in your screen. Here is an example, this is implemented in a docking container in a selection screen, but it would be the same if you were to attach it to a custom container in your dynpro. Simply create these objects in the PBO of your screen.

Cut and paste this program in to your system and run it.

* Variable for "Text Container" Abap Object
data: editor type ref to cl_gui_textedit,
      docking type ref to cl_gui_docking_container.

data: wa_text like tline-tdline.

data: begin of lines occurs 0.
        include structure tline.
data: end of lines.

data: textlines like tline-tdline occurs 0.
data: syrepid type sy-repid.

parameters: p_check type c.

at selection-screen output.

  syrepid = sy-repid.

  check docking is initial.

  create object docking
              exporting repid     = syrepid
                        dynnr     = sy-dynnr
                        side      = docking->dock_at_left
                        extension = 500.

  create object editor
      exporting parent = docking.

  perform set_text.

  perform write_text.

************************************************************************
*       FORM write_text                                                *

  data: modified type i.

* Retrieve text from container

           others             = 1.

* Write out contents of text editor
  leave to list-processing.
  loop at textlines into wa_text.
    write:/ wa_text.
  endloop.

endform.

************************************************************************
*      FORM  SET_TEXT

* Here use the READ_TEXT function module to get the text for your
* long text.  In this example, I'm filling the text manually

  lines-tdline = 'Here we are filling the text editor - Line 1'.
  append lines.

  lines-tdline = 'Here we are filling the text editor - Line 2'.
  append lines.

  loop at lines .
    shift lines left deleting leading space.
    append lines to textlines .
  endloop.

* Fill container with text lines
  call method editor->set_text_as_r3table
     exporting
           table              = textlines
           exceptions

endform.

Hi,

use FM read_text Fm to read long text

check table stxh,stxl.

use read_text function module to read text lines

edit_text to edit existing text

CALL FUNCTION 'READ_TEXT'

EXPORTING

ID = 'ST'

LANGUAGE = SY-LANGU

NAME = THEAD-TDNAME

OBJECT = 'TEXT'

TABLES

LINES = TLINE_TAB

EXCEPTIONS

ID = 1

LANGUAGE = 2

NAME = 3

NOT_FOUND = 4

OBJECT = 5

REFERENCE_CHECK = 6

WRONG_ACCESS_TO_ARCHIVE = 7

OTHERS = 8.

Regards

You can use <b>RKD_WORD_WRAP</b> after <b>READ_TEXT</b>...That way you can have multiple lines and maybe use a Table Control -;)

Hi asha,

first create a conntainer on the screen in which you want to display the long text.

write the following code in PBO.

IN TOP INCLLIUDE DECLARE THIS

DATA : TEXTEDIT_CUSTOM_CONTAINER1 TYPE REF TO CL_GUI_CUSTOM_CONTAINER.

DATA : G_CONTAINER2 TYPE SCRFNAME VALUE 'TEXT_EDITOR2' ,

TEXT1111 TYPE REF TO CL_GUI_TEXTEDIT ,

G_CUSTOM_CONTAINER2 TYPE REF TO CL_GUI_CUSTOM_CONTAINER .

DATA : TEXTEDIT_CUSTOM_CONTAINER1 TYPE REF TO CL_GUI_CUSTOM_CONTAINER.

DATA : editor1 type ref to cl_gui_textedit.

CONSTANTS : line_length1 type i value 128.

TYPES : BEGIN OF my_table_struct_definition1,

LINE1(line_length) TYPE C,

END OF my_table_struct_definition1,

MY_TABLE1 TYPE my_table_struct_definition1 OCCURS 0.

DATA : MYTABLE1 TYPE MY_TABLE1.

Class CL_GUI_CONTROL definition LOAD.

Class CL_GUI_OBJECT definition load.

DATA : V_REPIDD LIKE SY-REPID.

V_REPIDD = SY-REPID.

if editor1 is initial.

CREATE OBJECT TEXTEDIT_CUSTOM_CONTAINER1

EXPORTING

CONTAINER_NAME = 'TEXTEDITOR2'

EXCEPTIONS

CNTL_ERROR = 1

CNTL_SYSTEM_ERROR = 2

CREATE_ERROR = 3

LIFETIME_ERROR = 4

LIFETIME_DYNPRO_DYNPRO_LINK = 5.

IF SY-SUBRC NE 0.

add your handling

ENDIF.

create calls constructor, which initializes, creats and links
a TextEdit Control

CREATE OBJECT EDITOR1

EXPORTING

PARENT = TEXTEDIT_CUSTOM_CONTAINER1

WORDWRAP_MODE = CL_GUI_TEXTEDIT=>WORDWRAP_AT_FIXED_POSITION

WORDWRAP_TO_LINEBREAK_MODE = CL_GUI_TEXTEDIT=>FALSE

EXCEPTIONS

OTHERS = 1.

refresh mytable1.

endif.

IF SY-SUBRC NE 0.

CALL FUNCTION 'POPUP_TO_INFORM'

EXPORTING

TITEL = V_REPIDD "--> program name

TXT2 = SPACE

TXT1 = 'Error in flush'.

ENDIF.

IF YOU ARE RETRIEVING THE DATA FROM ZTABLE USE THIS CODE IMMEDIATELY AFTER THE ABOVE CODE .

ELSE YOU CAN USE READ_TEXT IN YOU HAVE OBJECT CREATED FOR LONG TEXT.

DATA : MYTABLE2 LIKE mytable WITH header line.

CLEAR MYTABLE2.

REFRESH MYTABLE2.

LOOP AT ITAB99.

*INSERT ITAB99-ZTEXT1 INTO MYTABLE.

MYTABLE2-LINE = ITAB99-ZTEXT1..

APPEND MYTABLE2.

ENDLOOP.

MYTABLE1[] = MYTABLE2[].

call method editor1->set_text_as_r3table

exporting table = mytable1.

let me know if you are not successful with achieving the results

Thanks
