1、在程序里包含SLIS
type-pools: slis.

2、聲明主表和明細表


* Global structure of list
types:  begin of t_table,
                     tabname  like dd03l-tabname,
                     ddtext   like dd02t-ddtext,
                     as4user  like dd02l-as4user,
        end of t_table.

types:  begin of ud_struct,
                     position   like dd03l-position,
                     tabname    like dd03l-tabname,
                     fieldname  like dd03l-fieldname,
                     ddtext     like dd03t-ddtext,

                     keyflag    like dd03l-keyflag,
                     rollname   like dd03l-rollname,
                     domname    like  dd03l-domname,
                     datatype   like dd03l-datatype,
                     ddleng     like dd03l-leng,
                     checktable like dd03l-checktable,
                     decimals   like dd03l-decimals,
                     eddtext    like dd03t-ddtext,
                     dddtext    like dd03t-ddtext,
       end of ud_struct.
data:   gt_outtabt  type t_table occurs 0 with header line.
data:   gt_outtabf  type ud_struct occurs 0 with header line.

3、申明主表和明細表的名稱變量
        g_tabname_header type slis_tabname,
        g_tabname_item   type slis_tabname.

4、聲明主表和明細表連接關鍵字變量
data:   gs_keyinfo  type slis_keyinfo_alv

5 、設置輸出格式

6、具體完整樣例
