CTM optimizer Question: Urgent

[Former Member]

Hi All:

This is about a phrase on optimizer requirements on service.sap.com,

can anyone explain what does this means: <b>SAP APO Optimizers are single-process, that is, one Optimizer run uses only one computing process, although planners can run different Optimization jobs in parallel</b>.

What kind of different optimization jobs in parallel its talking about.

Thank you

It means that exactly one optimization job can be run at any one time to calculate a solution, the job cannot be split up and run in parallel to form one solution at the end.

However, multiple users can run their own jobs at the same time as other users (depending on your maximum user settings in the master data for the optimization server).

Hope that makes it clearer.

Hi Ian,

If you cannot split the problem, what are the "Methods of decomposition" in the optimizer profile? The methods of decomposition: TIme decomposition, Product decomposition, Resource Decomposition.... are these decompositions done by syste and not manually by user?

Thanks.

Decomposition is a planning method to split the problem into parts, each part is "solved" separately, however the solving is still done in a linear manner and not in parallel.

Hai,

Different optimization job in parallel would mean that the jobs can run parallely "without clash in location - product" chosen for the optimization job.

This means that selected location - product must be unique in each of the parallel jobs being run.
