I'm creating a map-reduce task in a sutelet and would like to take the user to the Map/Reduce Script Status page an ideas ??

You can easily recreate in a search (though you may not get the “Details” link in there), and then you can control the search filter parameters (by deployment id) and reveal the results in a sublist

@Sim Greenbaum There is a special Suitelet someone has built for this I believe.

You could just redirect to url with parameter for deployment or task id, e.g.

/app/common/scripting/mapreducescriptstatus.nl?primarykey={ScriptDeploymentInternalID}

or

/app/common/scripting/mapreduce/ui/MapReduceStatusDetail.nl?taskId={TaskID}

for the detail view

get the url from url.resolvetasklink and redirect using the generated url
