按照前人的指引，最近尝试了HR的两个增强。按同事以前写的文档，基本都能顺利完成。
记录几个地方：
1.信息类型0534 PM01增强的时候要针对28版本 不然会报一个错，HCMT_BSP_PA_XX_R0534结构不存在，而实际上SE11可以看到结构HCMT_BSP_PA_CN_R0534是存在的
2.标准信息类型的屏幕可以通过MP000100 、MP053400程序打开。在标准的2000上增强的子屏幕，则ZP053400程序可以打开。
3.PM01生成对象以后，如果删除了某些参考CI_PXXXX中的屏幕字段，激活屏幕以后，发现还是需要被删掉的字段。于是又重新在屏幕上画出来，结果发现PA30里面点击修改按钮以后，其他增强的字段都变为可输入的，只有后来补的这个字段灰色的，不可输入。后来只好重新生成对象。重新生成的时候，逻辑流，ZP053410/ZP053420/ZP053430/ZP053440等程序都会被覆盖。
如果发现要重新生成对象，最好先备份之前的代码。
增强标准屏幕，做完屏幕的设计后，PM01－》单个屏－》分配增强，一般都会分配到2000屏幕中去。
4.新增了一个9007的INFOTYPE，放到异动事件中。（原来想增强0000，结果发现不允许）。最初的时候，没有配置到PA30的菜单信息组中，则在PA30输入9007没有描述出来，但是屏幕可见。后来加到PA30的菜单中，输入9007就会自动带出信息类型名称来了。
