I'm always getting the REPORT_ERROR_VIEWS_ENGINE error when I'm running analytics report using a RightNowSyncPortClient from my application on C#.NET. I have checked the following:
~ the ClientInfoHeader
~ the report 'limit'
~ the report 'start'
~ the AnalyticsReportFilters
~ ensured that the report filters' Names, Operators and Default Values comply to my application's requirements
~ on debugging, at runtime, the filters DO have their Values and Operators as expected
Some more points:
~ the report with its Filters runs fine on RightNow and NOT through my application on C#.NET
~ weirdly enough, my application gives perfect results when I run it on my test interface of RightNow. ( I possess two RightNow interfaces -- one for testing and the other for, you know). mentioning this, I want to mention that I Exported the successfulanswergiving Report from test interface to my other interface and still cross-checked -- both reports were the same, and fine. Just that the test one made me happy and the other one made me stay awake till late in the night.
