Why does my Insights Backlog report contain N/A values?
The backlog dataset is based on ticket events. When the Backlog Status value is N/A, it means there was an event that GoodData did not recognize. The most common cause for an N/A value is a Zendesk system touch on a deleted ticket.
These N/A values are always associated with deleted tickets, but not all deleted tickets create N/A values. These values come from edge cases, not simple ticket deletions. They will not line up with any metrics in the account, and they do not mean anything on their own. Backlog N/A values can be safely ignored and filtered out.
