Resource categories handled by SNP


There are four resource categories in SCM, Production, Transportation, Storage and Handling. Does SNP handle all 4 categories? What does Heuristics, CTM, optimizer each handle? If they don't handle any why?

    CTM can only handle production resources.

    Heuristics can handle production resources and to a limited extent storage resources.(check out threads in the forum for this)

    Optimizer handles all the resources. The reason is that optimizer converts any supply chain problem into a LP OPT problem taking constraints into account in order of priority and objective functions.

    CTM does plain and simple demand supply matching and this can only happen in situations of transformation (read production) driven primarily at material constraints. CTM reduces all supply chain problems into material producing and material availability problem. The internal model is very different from LP OPT and hence only production resources are handled.

    Heuristics does infinite planning and takes into account even production resources in a second sweep of capacity leveling. This leveling is only possible for production resources and not for other kinds of resources.

    • Hi Srinivas,

      I am a little confused, as I thought the same like you about CTM only considering production resources.

      But now I read in the SAP Help in the CTM Master data part the following:

      "CTM uses production resources, handling resources, and transportation resources."

      What is true now?

      Kind regards, Johannes

    Hello there!

    As far as I know this depends on the version of SCM you are using. CTM, when talking about SCM 5.0, only uses production resources (in reality it uses production capacity described in the resource) Are you checking SCM 2007 help?

    Kind regards

    • I checked with SAP and they said that handling resources are not considered by CTM in SAP SCM 5.0, contrary to what the SAP help says. They promised to change it.

      So now the question is there, how can I avoid that CTM schedules a planned purchase requisition on a weekend, when I can't use a handling resource with an attached calendar. Or is there another option for that?

      Kind regards, Johannes

      Hallo Herr Beck,

      die definitiv Aussage ist; dass Handlings-Ressources (SCM 5.0) in CTM

      nicht berücksichtigt wird. Die zuständige Abteilung ist informiert um

      die Dokumentation zu aktualisieren.

      Mit freundlichen Grüßen,
