There is currently no "lookup" operation offered by the Utility task, meaning that any in-process lookups (e.g. for "match-and-attach") have to call the lookupObjects operation on the AWD Processing Service SOAP web service.
This creates an inefficiency as the call goes out of the container and back in through the web server, creating a new execution thread in the process, rather than being a simple inline call from the Service Engine.
Adding this operation to the Utility task then also avoids the need to import the WSDL for the AWD Processing Service (for this specific operation at least!) and configure the parameters from scratch - so from a user (process designer) perspective, makes process creation easier, as the operation is already "pre-configured" out of the box.
