SD 7.1: getting 'Could not find [Group]...' when accessing from email
I'm getting a Process Manager Error 'Could not find [Group] where [GroupID] Equal [40cd4429-9c96-483d-a660-faf1ea2bc233]' when using an emailed hyperlink to http://wal01apalt02.hgb.hs.int/ProcessManager/Reports/OpenProcess.aspx...
I'm not sure when this started to occur (it was first reported by a user some time before Christmas). The GroupID does not exist in the 'Groups' table although it may have done for a short while following an import of the whole of our AD after which I had to delete a large number of records from 'Groups' and 'UserGroups'. I have scanned every column of every table in the ProcessManager database and the string does not exist anywhere.
We're (still) running 7.1 SP1.
Any help would be appreciated.
