SAP CPS Job Definition Duplicate function grey out
I encounter an issue where some of the job definition can be duplicated but i would not be able to do so some job. The function duplicate to be grey out, anyone encounter same issue or have any idea what could cause this issue? From my checking in the help provided by SAP, it only that 'only custom and some built-in jobs can be duplicated" which no clear cut what this statement mean. Appreciate any input here.
