我在SAP成都研究院做过的CRM中间件的项目其实并不是很多:
1. 2013年下半年和2014年上半年曾经支持过中联重科和蒙牛的CRM项目相关的中间件问题;
2. 2014年上半年做过一个CRM物料主数据的中间件开发项目;
3. 2014年负责CRM物料主数据的维护工作。
这个列表里所有的文章都是我在实际开发或者项目过程中遇到问题后记录下来的心得。2013年直到清明节前，我其实对CRM中间件是一点都不了解的，但是我的老板Poseidon让我把这一块的知识空缺补上，因为将来成都团队需要负责中间件这块的维护和持续开发。
我先把SAP中间件培训教程CR500看了一遍，了解了一些基本概念。但是这个教程讲的比较笼统，对SAP中间件标准开发人员帮助不是很大。
于是2013年清明节的时候，我把CRM物料主数据这个模块收到的SAP内部测试人员报的所有的tickets搜索出来学习了一遍，一共有200多个。有25%的tickets是因为测试人员的配置不正确造成的。我借此又积累了一些如何处理形如”如果遇到XXX的错误消息, 可能是因为YYY配置出错造成”这类问题的经验。 当我把所有内部tickets过了一遍之后，对中间件的框架代码有了一定的了解，成为写下列这些文章的基础。
我遇到使用中间件时报错误信息的这类问题，分析过程也就下列两种办法:
1. 根据错误信息的technical信息作为关键字去Google或者SAP Community上搜索。如果别人也遇到过同样问题，那就能节省很多debug时间。
2. 自己debug。
CRM中间件的上传下载方向的定义，都是以ERP作为主系统(leading system)而言，所以从ERP上抓数据到CRM称为下载，从CRM主动发送数据到ERP称为上传。
以从CRM上触发从ERP系统下载数据为例。如果下载过程不能按照您期望的工作, 那理论上说，出问题的可能性有以下几种：
1. 代码在ERP上从数据库表中抓取数据时不能正常工作: 没有抓取到期望的数据;
2. 代码从ERP数据库表里成功抓取到期望数据之后，在把数据发送给CRM之前，由于种种原因(比如配置), 一部分数据被过滤掉了，根本没有发送到CRM;
3. ERP工作完全正常，期望的数据全部发送到CRM，但是CRM inbound处理时因为配置的原因，在处理这些数据或者试图存储到CRM数据库表时出错。
这三种可能性分别对应下图Point1，2，3。
调试的关键在于找到针对这三种可能性的调试入口，即在哪里设置断点。下面我的原创文章里有讲述。
