Jim Miller, Senior Solutions Architect at Perficient, recently wrote a blog post about sessions, calculations and filters in Framework Manager:
In Framework Manager, an expression is any combination of operators, constants, functions, and other components that evaluates to a single value. You can build expressions to create calculation and filter definitions. Acalculation is an expression that you use to create a new value from existing values contained within a data item. A filter is an expression that you use to retrieve a specific subset of records.
In his blog post, Jim goes into great detail on how to use IBM Framework Manager to perform your calculations. You can read his full blog post here.
