通过IDOC实现EDI与SAP集成(一)

EDI主要用于公司之间的数据交换。 例如：在SAP下销售订单处理期间，可通过EDI接口发送和接收各式各样的输出。

IDoc是一种信息系统之间(通常是ERP)进行事务性或数据交换使用的标准数据格式，其中比较公认的是符合EDI标准的IDoc。

IDoc是SAP接口功能中主要的组成部分，是一个依赖IDOC type的数据实例。

IDoc结构是SAP系统的标准，它由三部分组成。

Control Record： 控制记录字段的内容。可以认为是文件头，它包含发送和接收端，IDOC ID，发送日期等信息，当IDoc出被触发时，SAP会首先检查这些信息是否正确。

Data Record : 装载传输的数据。当发送或接收这些IDoc时，数据将会被解析到特定的数据段中。

Status Record： 用来记录IDoc从发送方到接收方的历史状态信息。
