What is the expected behavior of Data Snapshots?

Hi All,

The issue is that am trying to view a Deferred Work Item report and the Last Data Snapshot shows as Dec 14, 2015 on one and Dec 15,2015 on the other.

Other reports show current warehouse data. Why are these reports not getting current data?

Reviewed this which seemed to show a possible bug but could not find anything else on it:
https://jazz.net/forum/questions/130958/why-is-the-data-snapshot-for-reports-two-days-old

During the last 36 days the reports did update their snapshot to Jan 31st 2016. But I  think the only reason the snapshot changed on that date is because we just recently updated our RTC/RRC version to 5.0.2. Maybe?

What is the expected behavior of Data Snapshots?

The 'Last Data Snapshot' date in Deferred Work Items report is the last data point in the chart. The report shows the following information:

What does this report tell me?
"This report plots all work items which are deferred from the given iteration. Each data point represents one day, and the value is the number whose "planned for" attribute changes to another iteration during that day.
This chart may be useful in conjunction with other reports (such as those that plot the number of open work items over time). It can help you discover whether iteration targets are being met by deferring planned work items to the future rather than addressing them."


Last data point can be generated when there are some changes to the work items that belong to the selected iterations. If the change is in the Planned For attribute of the work item, the deferred work item count will increase; otherwise, it will not be included in the count.
