Resource categories handled by SNP

[Former Member]

Hi,

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?

Thanks.

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

Hi,

No, I checked the help of SCM 5.0. You can find it in the CTM > Master Data > Resources Section.

Also the release notes of SCM 5.0 say the following, which is also misleading. The first paragraph mentions handling resources, the second says they are not supported. Still a little unclear now.

Transport and Handling Resources in CTM

Resource Attributes: The transportation resource size is not considered.

Time-continuous, calendar, and mixed resources must have 100%

utilization and no unscheduled breaks. Goods Receipt for Production:

Goods receipt for a specific production plan is only considered if all

possible output products use the same handling resource. Only capacity

consumption for main output is considered. Especially, production at

another location with a handling resource at the planning location does

not create a goods receipt activity in the following scenarios: -

Co-products exist - Production version for production location exists

Supply Chain Viewer The supply chain viewer (transaction

/SAPAPO/CTMVIEWER) is not enhanced to display individual activities and

resource consumptions for external procurement

( Changed at 15.11.2005 )

Goods Receipt Times in CTM

The function “goods receipt times” is only supported if the following

conditions are fulfilled: 1. All possible output products (main output

products and co-products) of a SNP or PP/DS plan need to have the same

„goods receipt times“ and the same "receiving calendars". 2. This is

also necessary to consider in case one product is produced in another

location. Thus the product’s „goods receipt times“ and "receiving

calendars" need to be identical as well. Production in another location

is a function, which can be used to model a product, which is produced

in location A, but its output appears in location B. In case different

receiving calendars or receipt times are maintained for the out put

products of one plan the goods receipt times are not taken into account.

The master data checker of CTM is also checking this and comes back with

a message in case the times or the calendars are not identical. For

output products of different plans it is possible to have different

calendars or receipt times. But note only if the output products refer

to DIFFERENT plans. Note also: - Between the last activity of a plan or

PPM and the goods receipt activity it is not possible to have any kind

of break. This activities must follow seamlessly after each other. -

Handlings-resourses are not supported by CTM. - For planned orders only

goods reciept times are possible. Goods issue times does not exit. -

This behavior is not valid for procurement orders.

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.

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
