In the recent DFP v201302 release, we announced  that the ability to run sell through reports  (STRs) is now available via the API. This has led to a bit of confusion as some developers who are able to run STRs through the web UI received a ReportError.COLUMN_VIEW_NOT_ALLOWED  message when using these new dimensions through the API. We would like to clarify how you’ll be able to access STRs.Vincent Tsao , DFP API Team
