alternativeValueProducer is ignored. - alternativeValueProducer

The alternative value producer. Only used if ValueFilter is set to a valid filter and that filter resolves to false for the
entity passed into ProjectEntityProperty. Can't be null if valuefilter is specified - valueType
- Type: SystemType
