A developer needs to limit the of a DataRaptorExtract to a maximum of one result.

 Using the LIMIT filter on the Extract definition allows the developer to specify the maximum number of results to return from the DataRaptor Extract. Defining a formula with the Filter function is used to filter the results based on a condition. Using a Custom Output Type when creating the DataRaptor is used to define the structure of the output data. Setting the Limit Property on the Action that calls the DataRaptor Extract has no effect on limiting the results.
