snp process

[Former Member]

hi gurus,

can any body tell the whole process of snp, and also can any body give me the configuration guide of this snp material.

if any body given this i really appreciate in advance.

thanks,

This is the overall SNP Process:

Planning Area Administration:

Take all the necessary steps to set up your planning area. The planning area is the basis for all activities in SNP. It is a collection of parameters that define the scope of all planning tasks.

· SAP APO Master Data Setup:

Master data is a crucial aspect of the SNP component in SAP APO. You have to configure this master data very carefully to achieve satisfactory results. SNP master data includes information about locations, products, resources, production process models (PPMs) or production data structures (PDS), and transportation lanes.

·Model/Version Creation:

Before you set up the model in the Supply Chain Engineer (SCE), you have to create a model name and assign the model to at least one version. You can assign the model to several different versions for simulation purposes. The version is also used for releasing the demand plan (final forecast) to SNP and for releasing the supply network plan to Demand Planning.

·Supply Chain Model Setup:

You set up the supply chain model for SNP in SCE. There you assign the locations, products, resources, and PPMs or PDS to a model. You then add transportation lanes to link supply locations to demand locations, allocate products to the transportation lanes, and define quota arrangements.

·Release Forecast Data to SNP:

You release forecast data to SNP by first loading the data in a planning area in demand planning (DP) and then releasing it, or by directly releasing it from an InfoProvider. The data is often unconstrained by any production or distribution restrictions. This step can be executed by either the demand planner or the SNP planner.

·Definition of Planning Method and Profile Settings:

You choose whether you want to use optimization-based planning, heuristic-based planning, or supply and demand propagation as your planning method. You also decide if you want to perform safety stock planning before the Supply Network Planning run. You then make the settings in the appropriate profiles for each of the methods requiring settings. You can still change these profiles during planning for simulation purposes. You may need to define additional master data specifically for the method you are using.

·Supply Network Planning Run:

You perform the planning run once you have chosen the method and carried out the prerequisite steps.

The result of a Supply Network Planning run using the heuristic, the optimizer, supply and demand propagation, or Capable-to-Match is a medium-term production and distribution plan.

·Interactive Planning:

After the SNP run, you review the plan in the interactive planning desktop. If you run heuristic-based planning, you can also level capacities from the interactive planning table.

Release SNP Plan to DP:

You release the final supply network plan back to Demand Planning (DP) to compare the demand plan (without constraints) with the constraint-based supply network plan. Major discrepancies between these two plans could trigger re-forecasting, and, ultimately, re-planning. For example, you may want to release the supply network plan back to DP if the capacity situation is not sufficient to fulfill demand created by a promotion and you need to make adjustments to the promotion planning strategy.

Converting SNP Orders into PP/DS Orders:

This is not part of the SNP process since it can only be done in Production Planning and Detailed Scheduling (PP/DS). However, it is included in the cycle because this step is usually performed before running deployment and the Transport Load Builder.

In PP/DS, you convert SNP orders into PP/DS orders to make them available for Production Planning and Detailed Scheduling.

Deployment Run:

After production planning is complete and the system knows what will actually be produced (this information is saved automatically in liveCache), the deployment run generates deployment stock transfers.

·Transport Load Building:

The Transport Load Building (TLB) run groups the deployment stock transfers resulting from the deployment run into TLB shipments. You can also manually create TLB shipments for stock transfers that could not be taken into account during the TLB run due to specified constraints.

hi, bala kavi

Thanks for giving the whole process of snp process . i have very helpful for this process.

i have one more doubt for planing process.

could u explain the heuristic plan process, and deployment process in detail. so that am able to understand the planning process .

thanks in advance.

Heuristics is one of the planning algorithms in SNP. As you know that SNP is used to plan the supply chain..The heuristic is used as part of a repair-based planning process consisting of the heuristic, capacity leveling, and deployment. The heuristic run processes each planning location sequentially and determines sourcing requirements.The heuristic processing groups all demands for a given product at a location into one demand for the bucket. The heuristic run determines valid sources of supply and corresponding quantity based on pre-defined percentages for each source of supply (quota arrangements), or procurement priorities for transportation lanes and production process models (PPMs) or production data structures (PDS). The demands are then passed through the supply chain to calculate a plan. However, this plan is not necessarily feasible. The planner can then use capacity leveling to adjust the plan and formulate a feasible plan

After production is complete, deployment determines which demands can be fulfilled by the existing supply. If there are insufficient quantities available to fulfill the demand or the quantities available exceed the demand, deployment makes adjustments to the plan created by the SNP run.

The deployment run generates deployment stock transfers based on the SNP stock transfers that were created during the SNP run. The Transport Load Builder (TLB) then uses these deployment stock transfers to create transport loads, thus generating TLB shipments

Dear Kumar,

APO Supply Network Planning (SNP) integrates purchasing, manufacturing, distribution, and transportation so that comprehensive tactical planning and sourcing decisions can be simulated and implemented on the basis of a single, global consistent model. Supply Network Planning uses advanced optimization techniques, based on constraints and penalties, to plan product flow along the supply chain. The result is optimal purchasing, production, and distribution decisions; reduced order fulfillment times and inventory levels; and improved customer service.

Starting from a demand plan, Supply Network Planning determines a permissible short- to medium-term plan for fulfilling the estimated sales volumes. This plan covers both the quantities that must be transported between two locations (for example, distribution center to customer or production plant to distribution center), and the quantities to be produced and procured. When making a recommendation, Supply Network Planning compares all logistical activities to the available capacity.
