TABLES :sscrfields,ztmm0045,marc."引用数据表

*---form不可以做DATA定义。

PERFORM get_alv_select."第三步
PERFORM get_alv_lfc.   "第四步
PERFORM get_alv_reuse. "第五步


*---第一步：声明ALV相关变量---*

DATA:gt_fieldcat TYPE lvc_t_fcat,
     gs_layout   TYPE lvc_s_layo,
     gs_fieldcat TYPE lvc_s_fcat.

*---第二步：定义内表---*

DATA:BEGIN OF zmmd0006_alv OCCURS 0,"定义一个代表头的内表
       mandt     TYPE marc-mandt,     "集团
       werks     TYPE marc-werks,     "工厂

       zzsppm    TYPE marc-zzsppm,    "商品品名
       mc_zzbaxh TYPE marc-zzbaxh,    "物料备案序号

     END OF zmmd0006_alv.

DATA:gt_alv LIKE TABLE OF zmmd0006_alv WITH HEADER LINE."参考内表再定义一个内表


*---第三步：读取数据---*

*---第四步：格式控制，布局结构---*
