Based on feedback from many of our beta testers, we have made the IncludeZeroImpression field in KeywordReportJob and CustomReportJob accessible to all developers. Previously, this field was restricted to beta testers.
Please note that very large reports that include zero impression rows may fail (indicated by error code 112). If your report fails as a result of enabling this option, try breaking subsequent reports down into smaller queries/reports.
We are working to make this a more scalable solution. However, we (and several of you) felt it was important to expose this feature now despite this issue. We will notify you when scalability enhancements are released.
