'STRING_SIZE_TOO_LARGE' 通过 Excel Odata 连接访问 ABAP CDS 时

Question

我在现有的 CD 视图中添加了一个新的时间戳 dec-15 字段。当我尝试使用这个新字段作为过滤器通过网络浏览器访问它时，它会获取数据。但是，它在通过 excel 加载时给出 'STRING_SIZE_TOO_LARGE'。它显示数据预览很好。

可能是什么问题？

此外，我用其他机器试过了。在我自己的机器上，它在 excel 中给出错误 'property does not exist'，而在浏览器中工作。

显然，EXCEL 不能很好地处理 DEC15。我将它转换为 NUMC，现在工作正常。
