Currently I have the following scenario SCSM:
A Windows Server 2008 R2 Server
SCSM 2012 and Self service portal.
A Windows Server 2008 R2 Server
SQL Database SCSM
A Windows Server 2008 R2 Server
SCSM DW
About a month ago upgrade to SCSM 2012 R2 without any problem.
The day today generates a report a month ago, all tickets from the console of SCSM, I see that reports are empty, if the report was generated by a year earlier, the report does not show the latest information, based on this see the reports stopped after upgrading
to functional SCSM 2012 R2.
