備註

The FilterExpression element contains an expression that evaluates to a variant. The expression is evaluated for each instance within a group or for each row in a dataset or data region. It is compared to the values in the sibling FilterValues element using the operator from the sibling Operator element. Failed comparisons result in the instance or row being filtered out of the grouping, dataset, or data region.

The FilterExpression element cannot contain references to report items. When used in a dataset or data region, FilterExpression cannot contain aggregate functions, and when used in a grouping, it cannot contain the RunningValue or RowNumber functions.
