Override the lookupReference() method and implement it in the way described in [How to: Add a Lookup Form to a Control [AX 2012]](http://msdn.microsoft.com/EN-US/library/hh185372.aspx).

You can have an example from below location in AOT.

Forms → SalesTable → DataSources → SalesTable → Fields → DeliveryPostalAddress → lookupReference method.
