This test would be a nice thing to add since the model statement of procs like logistic and hplogistic support the / lackfit option to do an HL test.
Unfortunately I can't think of a workaround to make the Scorecard node use this option. But it is definitely on our list!
In the meantime, if you have access to SAS Credit Scoring for Banking, you will be presented with the results of this test by default.
Thanks,
