Hi Zhen, If you are including a Date segment in your report, you also need to include a DURING clause in your report query. Please see sample code snippet below:
report_query = ('SELECT Year, Date, DayOfWeek, MonthOfYear, CampaignId, CountryCriteriaId, CampaignName,' 'CustomerDescriptiveName, CampaignStatus, AdGroupId ,' 'AverageCost, Clicks, Cost, MostSpecificCriteriaId ' 'FROM GEO_PERFORMANCE_REPORT ' 'WHERE Year in [2016, 2017] *DURING LAST_MONTH'*) Also, you may refer to this guide <https://developers.google.com/adwords/api/docs/guides/reporting#date_ranges> for the possible date ranges that you can set in the DURING clause. I also recommend you to enable your SOAP logs so you can check for your detailed SOAP request and response. You can enable it by following the "How do I log SOAP interactions?" section of this document <https://github.com/googleads/googleads-python-lib#how-do-i-log-soap-interactions> .
