WIS 00501

Hi experts

When I trie to open a report or create a new report that points to a specific universe I get the following error:

"Impossibile trovare l'universo. Contattare l'amministratore di Business Objects. (Errore: WIS 00501)"

"Universe not found (Error WIS 00501) Error:INF"

I've also tried to import and export the univers but nothing changes.

I'm using BOXI 3.1 fp. 1.7

Please HELP!

ciao

Camillo
