Logical databases were once very popular. Complex selections were relatively easy to portray and effort-intensive reports were unnecessary. Users also appreciated the way dynamic selection worked, which encouraged developers to use the technique more and more. Starting from Version 7.50, SAP has now declared logical databases obsolete. Consequently, it advised against creating new logical databases, but allowed the old ones to continue as if nothing had happened. This, how-ever, is a security risk that could impact any report.
