Answer 1

The same thing can be done using Object Oriented ALV.
Following are the steps...
1. HANDLE_STYLE TYPE LVC_T_STYL.
DECLARE work area,and table
2.  DATA: LS_EDIT TYPE LVC_S_STYL,
        LT_EDIT TYPE LVC_T_STYL.
changing the style...
3.
LOOP AT IT_FINAL INTO LS_OUTTAB WHERE FLAG = 'X'.
    V_INDEX = SY-TABIX.
    LS_EDIT-FIELDNAME = 'MATNR'.
    LS_EDIT-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED.
    LS_EDIT-STYLE2 = SPACE.
    LS_EDIT-STYLE3 = SPACE.
    LS_EDIT-STYLE4 = SPACE.
    LS_EDIT-MAXLEN = 8.
    INSERT LS_EDIT INTO TABLE LT_EDIT.
    LS_EDIT-FIELDNAME = 'VBELN'.
    LS_EDIT-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENAABLED.
    LS_EDIT-STYLE2 = SPACE.
    LS_EDIT-STYLE3 = SPACE.
    LS_EDIT-STYLE4 = SPACE.
    LS_EDIT-MAXLEN = 8.
    INSERT LS_EDIT INTO TABLE LT_EDIT.
    LS_EDIT-FIELDNAME = 'POSNR'.
    LS_EDIT-STYLE = CL_GUI_ALV_GRID=>MC_STYLE_ENABLED.
    LS_EDIT-STYLE2 = SPACE.
    LS_EDIT-STYLE3 = SPACE.
    LS_EDIT-STYLE4 = SPACE.
    LS_EDIT-MAXLEN = 8.
    INSERT LS_EDIT INTO TABLE LT_EDIT.
    INSERT LINES OF LT_EDIT INTO TABLE LS_OUTTAB-HANDLE_STYLE.
    MODIFY IT_FINAL INDEX V_INDEX FROM LS_OUTTAB  TRANSPORTING
                                      HANDLE_STYLE .
  ENDLOOP.
assigning the style to Layout..
4.   GS_LAYOUT-STYLEFNAME = 'HANDLE_STYLE'.
Check the sample code..
create a screen 100, place a control on that and name it as TEST. and also activate the pf-status.
