创建BOL的步骤就不说了，自己找，学习这个之前，需要自己先找个SAP CRM资料预习一下
T-CODE:BSP_WD_CMPWB
1.创建组件：输入组件名：ZLYTEST03，点击创建按钮，回车，选择包和请求。。。回车，回车，回车，知道创建成功，进入组件里。
2.加入BOL：点击运行时资源库编辑器，点击修改右键'MODEL'，添加自建的或者标准的BOL。保存，F3退出一下，再进入，会带出BOL浏览器按钮。
3.创建视图：点击组件结构浏览器，选择视图，右键，‘创建搜索页面’，选择搜索节点和结果节点（此节点需要在BOL中添加）。单选或者多选。。选择需要做链接的字段（如无，则下一步），如果需要结果视图中增加按钮，可自行添加，点击继续，完成。
4.配置SEARCH界面和RESULT界面，需要那些字段自己加。
5.运行，会出现上面配置的搜索条件和搜索界面界面（如果是自己一个个建的，需要将查询和结果视图加到视图集中，将视图集加到WINDOWS中）
6.搜索代码实现：在查询视图的事件处理器中，重定义查询（如果已经在BOL里写了查询代码的，自行解决）

好了，到这里，搜索视图搞定了。。。可以运行起来看看了
