Flow text within selection sceen

Hey, Folks.

Is there a chance to have an input field with more lines on a selection screen? Like an input text box on va01-> head-> texts?

Let's say, users can type in a text which is printed on a form.

thank you for any ideas.

    Use class 'CL_GUI_TEXTEDIT'.

    Check the program 'DEMO_CUSTOM_CONTROL'

    You need to use class CL_GUI_TEXTEDIT or if you are working on ECC6 (Netweaver7) then please check demo program RSMDS_DEMO.

    Pl. follow the steps:

    Step 1 - Create a sub-screen using screen painter in the repot program.

    Step 2 - Set the size of the sub-screen.

    Step 3 - Place a custom control on the screen set its name to u2018C_CONTAINERu2019 and set the size of the custom control to the size of the required multi-line input output field.

    Step 4 - Save and activate the sub-screen.

    Step 5 - Code the Data Declarations

    Code snippet: -

    • Create a reference to the custom control

    DATA: v_text TYPE REF TO c_textedit_control.

    DATA: v_line(72),

    • internal table to hold user entered text

    i_tab LIKE STANDARD TABLE OF v_line.

    Step 6 - Define Selection Screen.

    Displaying a sub-screen in a sub-screen area on a selection screen is a special case of a tab-strip control on a selection screen. A sub-screen area on a selection screen, is defined using following statements:

    SELECTION-SCREEN: BEGIN OF TABBED BLOCK <sub_area>

    FOR <n> LINES,

    END OF BLOCK <sub_area>.

    Code snippet: -

    PARAMETER matnr LIKE mara-matnr.

    • Data transfer error. Your installation is faulty.

    SELECTION-SCREEN: BEGIN OF TABBED BLOCK sub FOR 6 LINES,

    END OF BLOCK sub.

    SELECT-OPTION DATE FOR SY-DATUM.

    Step 7 - Before the selection screen is displayed, the subscreen must be assigned to the subscreen area <sub_area>. This is done in the initialization event by using the components PROG and DYNNR of the structure <sub_area>, which is created automatically when the subscreen area is defined . The program name of the sub-screen screen is assigned to the component PROG, and its screen number to DYNNR.

    Then Create the Multi-line Input Output custome control instance and set its properties.

    The Constructor parameters are explained below

    a) wordwrap_mode can have following values.

    WORDWRAP_OFF = 0: No line break

    WORDWRAP_AT_WINDOW_BORDER = 1: Line break at the edge of the window

    WORDWRAP_AT_FIXED_POSITION = 2: Line break at a fixed position

    b) wordwrap_position Position for the automatic line break in a line (if <wordwrap_mode> = 2)

    c) wordwrap_to_linebreak_mode Converts soft line breaks to hard ones when you save in the R/3 System.

    0 or false: Soft line breaks are ignored when you save

    1 or true: Soft line breaks are converted to hard breaks when you save

    The method set_statusbar_mode allows to show or hide the status bar of the control. It has following parameter possible values.

    a) statusbar_mode

    True: Status bar visible

    False: Status bar invisible

    The method set_toolbar_mode allows to show or hide the toolbar. It has following parameter possible values.

    b) toolbar_mode

    True: Toolbar visible

    False: Toolbar invisible

    Code snippet: -

    INITIALIZATION.

    sub-prog = sy-repid.

    sub-dynnr = 110.

    • create an object of class c_textedit_control

    CREATE OBJECT v_text

    EXPORTING repid = sy-repid

    dynpro_container = u2018C_CONTAINERu2019

    wordwrap_mode = 2

    wordwrap_position = 70

    wordwrap_to_linebreak_mode = 1.

    • set the status bar display off

    CALL METHOD v_text ->set_statusbar_mode

    EXPORTING statusbar_mode = '0'.

    • set the toolbar display off

    CALL METHOD v_text ->set_toolbar_mode

    EXPORTING toolbar_mode = '0'.

    Step 8 - Code the flow logic of the sub-screen.

    Code snippet: -

    PROCESS BEFORE OUTPUT.

    MODULE PBO.

    PROCESS AFTER INPUT.

    MODULE PAI.

    Step 9 - Code the PBO and PAI modules.

    Code snippet: -

    ****PBO Module.

    MODULE PBO OUTPUT.

    CALL METHOD v_text ->set_text_as_r3table

    EXPORTING table = i_tab.

    ****Synchronize the front and back ends

    CALL METHOD c_textedit_control=>flush

    EXCEPTIONS

    flush_error = 01.

    IF NOT sy-subrc IS INITIAL.

    • Data transfer error. Your installation is faulty.

    MESSAGE a001(cndp).

    ENDIF.

    ENDMODULE. " PBO OUTPUT

    ****PAI Module.

    MODULE PAI INPUT.

    CALL METHOD v_es_1->get_text_as_r3table

    IMPORTING table = i_sys_1.

    ENDMODULE. " PAI INPUT

    Step 10 - Save and activate the program.

    Regards,

    Joy.
