device and advertiser_channel column in adwords

[y_z...@septeni-original.co.jp]

Hi, I am a enginner of Septeni Original,Inc. And I am working on the data or adwords.

I had found that there are some data we took from Google API with blank device and advertising_channel columns, I want to know why these data exist and the condition we took these data.

Thanks very much.

Hello,

Device segments data by device type. Advertising channel refers to campaign type. Can you please share the report query you used so I can see why you are getting blank values for these fields? 

Thanks,
