Iterates through the specified child business objects, evaluating the expression in the context of each of the child business objects. The results of the expression evaluations are aggregated using the aggregatorFunc parameter.
Evaluates an expression for each selected object instance related to (a child of) a parent business object and applies an aggregator function to the results. The childPredicateExpression parameter, if specified, selects which related objects to include. If not specified, they are all included.
