Question

我有一个包含标题和数据的平面文件架构。我通过将属性min更改为0来使一些数据字段成为可选的。它我尝试在标题和标题详细信息属性中执行相同的操作，但它没有工作我还需要改变什么？

这是架构的一部分。包含header，headerdetails和数据节点属性，每个必需的第一个字段以及我想要的第一个trailling字段是第7个

我希望接受此文件。但目前这是有效的

因为biztalk正在寻找使用第一个文件的分号分隔符，所以第一行数据（前6个）被视为标题的一部分。这就是为什么我必须添加额外的分号，如第二张图所示。

Answer 1

嗯......什么样的平面文件？那是什么意思＆＃39;可选＆＃39;？

您通常不能将平面文件字段设为可选，除非它们是尾随字段，并且第一个和所有后续字段都是可选的。

这是因为所有平面文件都是位置敏感的。 Field＆＃34;名字＆＃34;总是在第8位，不能转移到7，因为6是可选的＆＃39;。

在flatfile架构的标头上创建一些可选字段
