I have a Google Ads account which has a single Smart Campaign and multiple usual campaigns. Also I've set up a data transfer to Google BigQuery. When I try to compare BigQuery data using the query
SELECT sum(Cost) FROM `project.dataset.AccountBasicStats_XXXXXX` where Date between '2021-12-01' and '2021-12-31'
the query result shows a less cost than I see in the Google Ads interface for the same time period. The difference is equal to the spend of my smart campaign. To check this, I've tried the queries:
SELECT * FROM `project.dataset.CampaignBasicStats_XXXXXX` where Date between '2021-12-01' and '2021-12-31' AND CampaignId = {ID of my smart campaign}
SELECT * FROM `project.dataset.CampaignStats_XXXXXX` where Date between '2021-12-01' and '2021-12-31' AND CampaignId = {ID of my smart campaign}
The both give me no results.
Is it true that BigQuery data transfer discards the data of smart campaigns? What are other ways to get statistics for them?
