Highlight individual table control field

The example below sets the EBELN field on the 3rd row of the table control to not be an input field. This is a fairly simple process which involves firstly calculating which row of the internal table is displayed at the top of the table control. From this you can work out which itab row is on the 3rd row and set its attributes using the LOOP AT SCREEN command.

Based on the example table control the ABAP code for this will be as follows, resulting in a modified version of the PBO MODULE 'populate_screen'.



   MODULE populate_screen OUTPUT.
    DATA: ld_line TYPE i.

*   Set which line of itab is at the top of the table control
    IF sy-stepl = 1.
      tc100-lines =
        tc100-top_line + sy-loopc - 1.
    ENDIF.

*   move fields from work area to scrren fields
    MOVE-CORRESPONDING wa_ekko TO ztc_ekko.

    ld_line =  sy-stepl + tc100-top_line - 1.

*   Changes individual field attributes of table control,
*   Sets EBELN field on 3rd row of TC to not be an input field!
    LOOP AT SCREEN.
      IF ld_line EQ 3.
        IF screen-name EQ 'ZTC_EKKO-EBELN'.
          screen-input = 0.
          MODIFY SCREEN.
        ENDIF.
      ENDIF.
    ENDLOOP.
  ENDMODULE.                 " populate_screen  OUTPUT
