[案例] 从EDI技术角度实现艾可迅/ACOM EDI项目VDA 4913 报文解析?

如何读懂艾可迅/ACOM EDI项目中的4913报文?一文中,已经对VDA 4913(发货通知Despatch Advice)报文进行了业务层面的详细介绍。本文会从EDI技术实现角度出发,依照VDA 4913(发货通知Despatch Advice)报文在EDI系统中生成的工作流程开展详细的描述。

首先您可以先下载并安装  知行EDI系统免费30天试用版 。然后创建以下端口,根据下面描述的报文转换过程操作一遍,以便深入了解。

  • Excel端口:根据所有数据节点映射关系,将数据从Excel格式转换为标准XML格式。
  • VDA端口:实现VDA标准报文和XML格式文件的转换。
  • OFTP端口:通过互联网使用OFTP传输协议与交易伙伴建立EDI连接。

报文转换过程

将用户自定义Excel格式的文件转换为艾可讯/ACOM需要的VDA 4913(发货通知Despatch Advice)报文,工作流程主要分为以下4个步骤:

1.填写自定义的Excel格式文件,上传至Excel端口并发送:

供应商可以根据自身的实际需求去设计Excel的填写模板,对于每个业务字段也可以有自己的命名方式。可以选择手动填写数据,也可以和ERP系统集成,在字段映射关系正确的情况下,将ERP系统导出的数据直接填写进Excel模板中,这样既方便操作,又可以增强数据的可读性。

知行软件的Excel端口会帮助您将Excel格式的文件转换为标准XML格式的文件。在转换之前,用户首先需要在Excel端口的“输入”界面中,将Excel文件上传,选择上传的文件点击“Send”发送。Excel端口会根据之前写好的Mapping Code(映射代码),将Excel格式文件中的数据映射进对应的标准XML格式字段中。

关于映射代码,知行的EDI技术人员会根据艾可迅/ACOM所提供的VDA 4913(发货通知Despatch Advice)报文规范上的字段去做映射;并且根据VDA 4913(发货通知Despatch Advice)报文规范中字段的类型(如必填或可选)、数字的小数位精确程度、是否可以为空等具体要求对所填写的数据进行判断,如果符合报文规范上的一系列要求,则可以成功发送至下一端口并进行后续的操作;如果有一处不符合报文规范中的要求,则会根据判断语句中的报错信息进行提示,并且会在Excel端口的发送过程中出现“Send Error”提醒,这样用户就可以根据报错信息准确的定位出现错误的位置及原因。

2.成功转换的标准XML格式示例文件如下:

下面是Excel端口输出的VDA 4913(发货通知Despatch Advice)标准XML格式文件。将Excel文件先转换成标准XML格式文件,而不直接转换成EDI报文,其中一个原因是因为标准XML格式是被大部分人所接受的,相较于EDI报文来说,标准XML格式的文件更易于理解,也可以应用于其他本地化开发中。

3.由标准XML格式文件转化得到的VDA 4913示例报文如下:

供应商将填写好的Excel文件通过Excel端口成功发出之后,文件就会被转发到VDA端口。在VDA端口的Settings配置界面中,通过配置Sender Identifier(发送方标识)和Receiver Identifier(接收方标识),在生成VDA 4913(发货通知Despatch Advice)报文的过程中,会自动把配置好的信息映射至对应的字段中。

VDA端口Settings配置界面如下图所示:

知行软件的VDA端口可以自动将标准XML格式的文件转换为VDA标准下的4913报文,并根据Mapping Code(映射代码)中每个字段不同的补位方式去进行自动补位,不需要用户手动的去计算每一行是否为标准的128个字符。报文中字段结构出现的先后顺序也必须遵守VDA 4913(发货通知Despatch Advice)报文规范中的要求。

由标准XML格式文件转换得到的VDA 4913(发货通知Despatch Advice)报文截图如下:

4.将VDA 4913(发货通知Despatch Advice)报文由OFTP端口发出:

VDA 4913(发货通知Despatch Advice)报文在VDA端口成功发出之后,就会转发至OFTP端口。在OFTP端口的Settings配置页面中,用户可以通过配置合作伙伴的SSID、密码、证书等参数信息,与合作伙伴成功地建立连接,实现数据的自动化传输。
