我已经修改了以下App Engine程序，以使用文件布局更新现有行上的字段。我已添加代码来更新已填充新供应商项目ID的项目的现有行。尽管程序在运行时不会出错，但实际上也不会使用ITM_ID_VNDR字段更新表PS_ITM_VENDOR。该程序将适当地读取文件布局，并且我可以显示ITM_ID_VNDR的变量。我不确定我是否为CreateRecord类正确使用了.Update方法。更改由底部的“ 1/7/2020”注释标记。

更新：我可以在跟踪文件中看到，在尝试更新时，我没有选择表的关键字段。我认为这是问题的一部分...

认为我已经发现了这个问题，我需要按如下所示将＆REC1绑定到＆REC2：
&REC1 = CreateRecord(Record.ITM_VENDOR);
&REC2 = CreateRecord(Record.ITM_VENDOR);
.....
&REC2.Update(&REC1);
