Without knowing what information you want, I agree with Haritha. You can also get the name of the SLA from the pxAssignSvcLevel property. If you want to open the SLA queue item itself, you could do that, but that will require a bit more work. You can use the pxAssignmentHandle on the queue item to tie it to the pxAssignmentKey on the pxFlow page of your work object. From there, you have many more aspects of the SLA to make use of.
