Description

Indicates whether the aggregate value is currently available.

Read InUse to determine whether the Value method returns a summarized value. When InUse is false, Value returns Null. When InUse is true, the aggregate is maintained so that it calculates the formula specified by Expression for the current set of records, including any edits to records in the current group.
