We are trying to pull in all Keyword performance data into our data lake for analytical purposes and would like all attributes. However, we understand that there are several fields that are mutually exclusive and thus we cannot pull all metrics in one API call. We also saw that there is documentation here:
https://developers.google.com/adwords/api/docs/appendix/reports/keywords-performance-report which indicates which fields are not compatible. We would like to know if there is documentation anywhere that highlights what can and cannot be pulled to get all attributes of the report. We can go through every report and identify fields compatible and not compatible, however this will be very time consuming and we are hoping that someone else has run into a similar challenge we can learn from. :D
