Symptoms
Try to schedule a Change Order on Renewal date shows following message in UX1:
You has passed the cancellation window for reducing seats for this subscription
Cause
This is caused by software issue #PDI-2035 or #PDI-2096. PLM sends draft request to Connect with planned_date as null so it is not considered as a scheduled for renewal change but immediate.
Resolution
Immediate work around to place order is click 'Next' button again, at second attempt to validate the order the planned_date is passed to the Connect request.
Software issue #PDI-2035 is planned to be fixed in PLM version 1.11.
Software issue #PDI-2096 is planned to be fixed in PLM version 1.12.
