Hi Stacey
If DEV is working and PRD is not have you gone through and compared both and ensure latest MSMP configuration in PRD has been activated?
Also, is the approver COCHGG00 also the Role Owner?
Are you able to show you MSMP configuration? It's makes sense to analyse the log in the context of your configuration. E.g. does the Z_ADDTNL_ACCESS_PATH path have two stages: Manager and Role Owner of which there is a routing rule on the Manager approval to go to the NO_ROLE_OWNER path where the business role has no role owner?
