HELLO, 这里是百里一个学习中的ABAPER,这里记录工作学习中遇到的bug,知识内容等内容.今天讲的是在工作中经常会使用的数据下钻,通过跳出小界面的方式展示关联数据.今天结合工作经验这里做下技术总结.

下钻简介

在ALV报表展示中.会出现关键字段下钻,展示某个界面或者系统自带界面.此时需要给增加 user_command 事件. 下钻内容包括,展示具体某个界面,系统界面,与关键字对应的ALV界面.

技术介绍

下钻弹窗数据展示的关键技术为调用函数 cl_salv_table=>factory 展示一个新的ALV容器数据. 首先先跟本身第一层开发ALV方式一样, 定义默认基础数据集,权限检查,定义ALV layout ,fieldcat 等相关属性内容. 同时设定对应的staus 及usercommd 方便操作用户事件.设定第一层ALV展示数据的基础上,设定hot字段,在按照关键字段关联对应下一级ALV展示数据.

TRY.
cl_salv_table=>factory(
IMPORTING r_salv_table = go_alv "导出ALV的容器对象
CHANGING t_table = lt_item[] ). "内容表 
CATCH cx_root INTO cxroot. 
excmsg = cxroot->get_text( ). 
MESSAGE e000(oo) WITH excmsg. 
ENDTRY.
go_funlst = go_alv->get_functions( ). 
go_funlst->set_all( 'X' ).

实例展示

此例子第一层为VBAK 表 VBELN 字段,第二层内容为对应VBELN 单号对应的料号数据及料号长描述例子.

创建数据集

设定ALV 定义相关结构,工作区内表.同时定义必要字段如ALV展示相关变量.usercomed 变量.格式及样式变量字段.

设定选择屏幕

筛选关键字段,where 条件.

*--------选择条件

结果展示

如图展示内容结果,一级对应的字段为,VBAK 表中的销售订单,创建日期,销售组织,销售办事处,创建人等字段, 通过usercomed ,双击数据VBELN下钻到下一层ALV数据. 下层ALV数据展示内容为销售订单凭证,行号,料号,目标数量,同时可以使用 go_alv->get_columns( )->get_column( 'MAKTX' )->set_long_text( 'TES删除' )." 给对应的字段附加更换列名.
