Mapping Rule Built-ins for Advanced Multi-Valued Fields - RapidIdentity Platform Documentation

The built-ins in the following table work when the input data contains multiple values that have their own sub-fields (an array of objects):

Built-in Name	Arguments	Outputs	Example
anyChildContains	Name of sub-field to match; value to look for	true if any child contains a sub-field that exactly matches the given value, false otherwise	orgs.anyChildContains("sourcedId", "1234")
anyChildContainsText	Name of sub-field to match; substring value to look for	true if any child contains a sub-field that partially matches the given value, false otherwise	orgs.anyChildContainsText("type", "district")
mapWithSelector	Sub-field to extract	Flattened array of strings that contains only the values of the given sub-field	orgs.mapWithSelector("sourcedId")
