TableFilter data type

I’ve noticed in Attain 3.01 a new data type in the data type drop down list in the table designer called TableFilter. I can’t find any reference to this in the online help or the application designer’s quide. I would appreciate any insight into this data type and how it can be used.

This type was added to support record level security only, and is used in the Permission table. It is not intended for general use, but is able to be used in any custom table for the same purpose, theroetically. It is mentioned in the Installation and System Management manual as part of record level security.
