Hi again. I tried your suggestions. Now I get the proper costs (according to the adwords UI) for Total - Search and Total - Shopping. However, Total - Display Network doesn't match.
I'm using awql like this
SELECT AdGroupId,AdGroupName,CampaignId,CampaignName,Device,Clicks,Cost,Date FROM DISPLAY_KEYWORD_PERFORMANCE_REPORT WHERE AdNetworkType1='CONTENT' DURING 20150601,20150601
The cost I get is $106.54 when the adwords UI says $2,764.24. Clicks are way off too, 208 vs 3969.
Something must be missing in my query - any ideas?
