With IDs in reports developers can get a full snapshot of their account activity by scheduling a single report. However, please bear in mind that if a Keyword did not have any impressions during the specified period the Keyword will not appear in the report. Also, please remember that while Keyword IDs are unique within an AdGroup they are not globally unique. To properly identify a Keyword both the Keyword ID and AdGroup ID must be used together.
Enjoy the new report features, and please keep the feature suggestions coming!
