Is there additional set up required in Rally when you configured the integration between Rally and Clarity, configured the attribute mapping attributes, and run the Synchronized Mapped Information job but the job does not fetch any data from Rally?
Release : 16.0.1
Component : Clarity Add-Ins (PMO, Rally)
In Rally check the fields 'Integration Mappings' and 'Ready' in order for the integration to fetch data. See also, Run the Import Integration Mapping Job in Classic PPM.
