Optimization Run

[former_member182449]

Dear Expert,

You execute the optimization interactively in the planning board and planning table, and in the background for the production planning run.

Please let me know Definition of the processing steps ? to run optimization in production planning run.

Please give me Details .

Thanks

Hi,

As you know, we can define multiple steps in Production planning run.

While defining your variant, in the first step, it is always a good practice to run the low-level code heuristic. Maintain your selection here.

In the second step, you can run the production planning heuristic.

After running the PP heuristic, it is better to run the optimization. For this, you have to assign your optimization profile in the PP planning run step.

While scheduling this PP planning run , optimization will run automatically in the background.

Hope this detail will help you to understand the steps.

Dear Sir,

Thanks Alot for your response

Could you please tell me what's the heuristic should be run in the second step with optimization profie ?

Appreciate your effort

Hi,

There is no need to run heuristic with Optimization run. But before running the optimizer, we have to run some PP heuristics like SAP_MRP_001, SAP_PP_002 and SAP_PP_003.

The below is the example from SAP study material,

The objective of a production planning run is generally to create a “feasible” demand
program. The actual planning is normally broken down into several steps, like in the
sample process given:
• To ensure consistent planning, the stage numbering algorithm for determining
the low-level codes must be executed regularly. This algorithm may, for
example, be scheduled either at the start of a planning run or separately at
regular intervals (weekly).
• Normal material requirements planning is carried out with the SAP_MRP_001
heuristic. This planning is executed infinitely.
• In order to link the created structure of requirements and requirement coverage
elements with each other on multiple levels (and therefore to be able to optimize
on multiple levels later on), a heuristic for creating fixed pegging is used.
• The capacity planning step can be carried out with the optimizer, which, in
addition, can carry out simultaneous sequencing with regard to setup times
or scheduling delays.
• Following optimization, the fixed pegging edges utility is removed again.
There can be further steps. When setting up a planning run such as this, it is
recommended that a step-by-step approach be taken so that the results of the individual
planning steps can be verified in the test phase.

Hope it will give answer for your question.
