CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING

一般调用：

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_structure_name   = 'KKBCS'
      it_fieldcat        = lt_field
      is_layout          = gs_layout
      i_callback_program = sy-repid
      i_grid_title       = ''
    TABLES
      t_outtab           = gt_kkbcs[]

3.OO方式的alv：set_table_for_first_display

ls_variant-report = sy-repid.
 
CALL METHOD gc_alvgrid->set_table_for_first_display
    EXPORTING
      is_layout       = ls_layout
      i_save          = 'A'          "设置成A
       is_variant       = ls_variant  　"这个参数也必须输入
    CHANGING
      it_outtab       = git_item[]
      it_fieldcatalog = git_fieldcat[].

4.FUNCTION 'LVC_FIELDCATALOG_MERGE' 根据表结构生成fieldcat

CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
    EXPORTING
      i_structure_name       = 'ZSSD028'
    CHANGING
      ct_fieldcat            = gt_fieldcatalog[]
    EXCEPTIONS
      inconsistent_interface = 1
      program_error          = 2
      OTHERS                 = 3.
