Symptoms
Downgrade order was placed only for 1 resource, but in the order several other resources are added. Why this happens?
Cause
Other resources depend on resource that is being downgraded and they are added automatically to the downgrade order.
Resolution
List of all resources that depend on downgraded resource can be found in PBA Home> Product Director> Resource Manager> Resources> select_resource_you_want_to_downgrade > Necessary To.
