App Designer prompts for record tablespace name

PeopleSoft is a cross platform application, and some databases use tablespaces and some do not.  This error will commonly occur when using Microsoft SQL Server, and to fix this navigate to:

PeopleTools > Utilities > Administration > PeopleTools Options

Uncheck Platform Compatibility Mode

You should now be able to save your record without being prompted for tablespaces what are not present in your world!
