你好，

谢谢你的问题。如果您在处理之前轮询性能数据，则预计报告将不包含任何数据。当您轮询当天的数据时，通常会出现这种情况。请参阅下面的文档，其中解释了
对数据检索的期望。

Thank you for your question. It is expected that if you poll for Performance data before its processed, the report will not contain any data. This is usually the case when you poll for data for the current day. Please see the below documentation, which explains the expectation of data retrieval.

如果不是这种情况，并且您在Bingads.com上看到数据且KW报告未返回数据，请报告此问题。

If this is not the case, and you are seeing data on Bingads.com and the KW report is not returning data, report back this issue.

谢谢，

Itai
