KB 4010426 added the ability to rate route plan with change management enabled - previously, you would receive error:
“Change to the document are only allowed in state Draft, because Change management is activated.”
You can now rate after installing the KB, however, you cannot have charges flow back to the PO ("Add Transportation Charges to orders") with change management enabled. The same error occurs.
This has been determined to be a feature gap that requires a design change. Please vote up if this is something that your business needs.
