We are using two version of BO: 3.1 and 4.1 SP5 FP7.
Generally when we have report in 3.1 we can refresh it in 4.0 also (of course there are two diffrent universes).
But sometimes I get very strange error. In 3.1 report work fine but when I open it in 4.0 ant try to refresh I got info:
'Some objects no longer available in the universe (WIS00001)'
It's strange because all objects exists in universe (in old one and new one) and I have to add missing objects one more time and report work fine, but it's very frustrating.
Do you have any idea what/why it happened?
