The "Lookups" menu option in the system designer gets duplcated upon upgrading to version 7.6.0

Symptoms

The "Lookups" menu option in the system designer gets duplcated upon upgrading to version 7.6.0

Cause

A "Lookup" package that has been deleted from version 7.6.0 and whose contents have been transferred to other packages, remained in the system.

Solution

If no client logic is bound to the schemas of this package, delete the "Lookup" package dependencies to other configuration packages and afterwards delete the package itself.

Necessary conditions and possible resitrictions

Prior to getting down to the solution implementation, make a database backup. After you implement the solution, perform the "Compile all items" action. If there exists any client logic bound to the package, additional analysis is needed.
