Changing Font style in ALV

By Joyjit Ghosh, IBM India

By using the Function Module REUSE_ALV_GRID_DISPLAY_LVC we can change the font style in ALV report. 

Example:

*&---------------------------------------------------------------------
*& Report  Z_DEMO_ALV_JG                                               
*&---------------------------------------------------------------------
REPORT  z_demo_alv_jg                           .
* Include for all style values
INCLUDE <cl_alv_control>.
* Internal table for final output data
DATA: i_flight TYPE STANDARD TABLE OF sflight.
* Internal table for field catalog info
DATA: i_fields TYPE lvc_t_fcat.
* Field symbol for field catalog
FIELD-SYMBOLS: <wa_fields> TYPE lvc_s_fcat.
* Select data
SELECT * FROM sflight
INTO TABLE i_flight
UP TO 100 ROWS.
IF sy-subrc = 0.
* Get field catalog
  CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
   EXPORTING
      i_structure_name             = 'SFLIGHT'
    CHANGING
      ct_fieldcat                  = i_fields
   EXCEPTIONS
     inconsistent_interface       = 1
     program_error                = 2
     OTHERS                       = 3
            .
  IF sy-subrc = 0.
*   Changing the style of field catalog
    LOOP AT i_fields ASSIGNING <wa_fields>.
      IF sy-tabix > 4.
        <wa_fields>-style  =  ALV_STYLE_FONT_ITALIC.
      ELSE.
        <wa_fields>-style  =  ALV_STYLE_FONT_BOLD.
      ENDIF.
    ENDLOOP.
  ENDIF.
* Calling the FM to display ALV report
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING
      i_structure_name = 'SFLIGHT'
      i_grid_title     = 'Style demo'(001)
      it_fieldcat_lvc  = i_fields
    TABLES
      t_outtab         = i_flight
    EXCEPTIONS
      program_error    = 1
      OTHERS           = 2.
  IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
ENDIF.
