1.进行ALV全局变量声明

DATA : l_pos TYPE i.
DATA : it_fieldcat_lvc TYPE lvc_t_fcat,
       wa_fieldcat_lvc TYPE lvc_s_fcat,
       wa_layout_lvc   TYPE lvc_s_layo.

2.设置字段属性，布局属性，显示数据

FORM frm_display_data .
  PERFORM frm_alv_setfield.
  PERFORM frm_alv_setlayout.
  PERFORM frm_alv_display.
ENDFORM.  

首先设置字段属性：

FORM frm_alv_setfield .
  l_pos = l_pos + 1.
  wa_fieldcat_lvc-col_pos = l_pos.
  wa_fieldcat_lvc-fieldname = 'MATKL'.
  wa_fieldcat_lvc-scrtext_l = '物理组'.
  wa_fieldcat_lvc-scrtext_m = '物理组'.
  wa_fieldcat_lvc-scrtext_s = '物理组'.
  wa_fieldcat_lvc-just = 'L'.
  APPEND wa_fieldcat_lvc TO it_fieldcat_lvc.
  CLEAR wa_fieldcat_lvc.

  l_pos = l_pos + 1.
  wa_fieldcat_lvc-col_pos = l_pos.
  wa_fieldcat_lvc-fieldname = 'WGBEZ'.
  wa_fieldcat_lvc-scrtext_l = '物料组描述'.
  wa_fieldcat_lvc-scrtext_m = '物料组描述'.
  wa_fieldcat_lvc-scrtext_s = '物料组描述'.
  wa_fieldcat_lvc-just = 'L'.
  APPEND wa_fieldcat_lvc TO it_fieldcat_lvc.
  CLEAR wa_fieldcat_lvc.
  ...
  ...
  ...
ENDFORM.

其次设置布局属性：

FORM frm_alv_setlayout .
  wa_layout_lvc-zebra = 'X'.
  wa_layout_lvc-sel_mode = 'A'.
  wa_layout_lvc-cwidth_opt = 'X'.
ENDFORM. 

最后就是显示数据：

FORM frm_alv_display .
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING
      i_callback_program       = sy-repid          " 当前程序
      i_callback_pf_status_set = 'FRM_SET_PF_STATUS_10016'
      i_callback_user_command  = 'FRM_USER_COMMAND_10016'
      is_layout_lvc            = wa_layout_lvc      " 属性内表
      it_fieldcat_lvc          = it_fieldcat_lvc[]  " 列明内表
      i_save                   = 'X'                " 是否保存布局
    TABLES
      t_outtab                 = gt_mara             " 数据内表
    EXCEPTIONS
      program_error            = 1
      OTHERS                   = 2.
ENDFORM.                    " FRM_ALV_DISPLAY

套路就是这样！！！
