We recently upgraded to v4.0, Oracle. Since that time reports that link to more than 1 table run extremely slow. Example: 3 tables, 7 derived fields. Ran in less than 2 minutes under version 3.0. Now it ran 1 hour before I kill it. The report will run in 20 minutes if I specify the company codes. ADP seems to be at a loss. Any suggestions as to where we can look?
