Gets or sets expression to evaluate globally for the report or for each
group instance.
Unlike expressions evaluated in visual elements of the report,
each instance of this expression is calculated only once when
the report is executed and never recalculated during subsequent renderings.
This is necessary for time-dependent calculations.
