We made a change to environment and shows us a universe
a folder called ‘key objects’ in it as objects ‘PK6742’ that correspond to keys defined in LOV’s, we returned for the rise of these universes and has not solved the problem
we have implemented the function "Aggregate Aware 'to improve performance in queries and with that change we have made a change of environment, that's all.
I’ve found the problem by making the change of environment, in a process of change had to lose ‘LOV’s’ containing the fields with multivalued and that is why Business Objects created a folder KeyObjects
I guess it’s a program error, does not understand even as it has been lost, but the solution is falling back and recreate the environment LOV’s, this is how we solved
Thanks for the replies and forgive my English is not very good
