SEGMENT_UNKNOWN 通过 JCO 连接器访问 SAP 后端时出错

Question

我正在尝试通过 Java 中间件 (Dell Boomi) 连接到 SAP 系统以检查现有文档类型。检查基本 IDOC 类型（例如 ORDERS05）时一切正常。当尝试检查自定义类型（例如 ZORDERS05）时，我从 java JCO 类:

得到一个相当模糊的异常

关于如何解决此问题的任何提示？ SAP 方面的对象似乎完全相同（都是基本类型，没有扩展等...）

Answer 1

Ravindra HV 的注释是正确的，此问题是由于 SAP 端的配置错误引起的。为了解决这个问题，SAP 团队必须在自定义 IDOC 类型中发布自定义段 (ZHEADER)。请参阅对此的回答：http://scn.sap.com/thread/3436578
