# ReferenceMemoryMappedType

The fields with this property hold a value that is an existing value in a different ReferenceType field.

IDOL Server uses this value in combination with the FieldRecurse action parameter and the field specifier MATCHRECURSE. You can also use it with the LINK field specifier, and the LinkFieldText action parameter to run linked queries.

NOTE: You cannot configure a field with more than one numeric-based field type concurrently. Numeric-based types include NumericType, NumericDateType, MatchType, ParametricRangeType, ReferenceMemoryMappedType, and ParametricType when the ParametricNumericMapping configuration parameter is set to `True`.
