We are trying to switch Service Plan for subscription however we cannot place order and getting following error:
There is an uncompleted Change Order #RCXXXXX related with Resource #YYYYY
There is old unprocessed resource order for this subscription. It might be in status Provisioning Failed or Cancelled. The issue is caused by #PBA-74673 ("ChPlanPeriodOItemOIID is not deleted when change order is cancelled by system").
Contact your Technical Account Manager or Pooled Technical Associate team at firstname.lastname@example.org to clarify the current status of #PBA-74673 and check for the possible temporary solution.
