Do Rally/AC feature dates update PPM task dates when the Synchronize Agile Central job is run?
The feature dates in Agile Central are not designed to update the PPM task start and end dates. They behave as two separate fields. The feature dates of AC are caught in the following fields in PPM:
'Agile Actual Start' | 'Agile Planned Start'
'Agile Actual Finish' | 'Agile Planned Finish'
