We have an issue with our current version of DPA (9.1.85) where history / trend information is not showing up beyond mid-April. I believe the data is present in the database as when a particular item, SQL statement, for example, is drilled into for a particular date, the detailed data information is there. However, selecting 'Historical Charts' also shows a lack of data beyond mid-April.
Any suggestions on how we can get the Trend information and Historical Charts features working properly again?
Many Thanks!
