如图所示

开发中遇到了需要以不同的维度去查询，形成的alv也需要根据业务人员自己形成固定的布局

实现方式

控制is_variant参数

 DATA:   ls_variant TYPE disvariant.

  IF c_kunnr IS NOT INITIAL.
    ls_variant-report = sy-cprog.
    ls_variant-handle = '1'.
  ELSEIF c_matnr IS NOT INITIAL.
    ls_variant-report = sy-cprog.
    ls_variant-handle = '2'.
  ELSE.
    ls_variant-report = sy-cprog.
    ls_variant-handle = '3'.
  ENDIF.

  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY_LVC'
    EXPORTING
      i_callback_program = sy-repid
*     i_callback_user_command  = 'USER_COMMAND'
*     i_callback_pf_status_set = 'SET_PF_STATUS'
      is_layout_lvc      = gs_layout
      it_fieldcat_lvc    = gt_fieldcat
      i_save             = 'A'
      is_variant         = ls_variant
    TABLES
      t_outtab           = pt_outtab[]
    EXCEPTIONS
      program_error      = 1
      OTHERS             = 2.
