You should maintain all the master data before you run the optimizer in Supply Network Planning. Like when you want to use Local time, you should set this indicator.

 

Following Master data should be created to run the optimizer −

 

• Location Specific − It includes the type of location, storage resource, handling resource, calendar and time zone, etc.

   

• Product Specific − It includes the master data related to attributes (weight of product, volume and unit, etc.) unit of measures, procurement related (procurement type, procurement costs, planned delivery time, etc.), SNP related master data and other product specific fields.

   

• Resource Specific − You have the master data specific to resource type - Bucket resources, single mixed resources, multi-mixed resources, etc.

   

Once a resource master data is created, you have to assign resources to the location master data.

 

Supply Network Planning Run

Different planning methods are available to run Supply Network Planning. These run can be performed using an application or also in the background. Common SNP planning run includes −

 

Optimization-Based Planning

This planning method is cost effective, which considers all the factors to find the most cost-effective plan. The optimizer considers the following points keeping the cost as a base factor −

 

• Which products are to be produced and the quantity of product transported, stored, and procured.

   

• Resources to be used and Production data structures to be used for production.

   

• Production location, storage and delivery, and source and destination locations.

   

Heuristic-Based Planning

In this planning method, we group all the demands for a product at a location into one demand for the bucket. The planning horizon and key figures on the basis of which heuristic is done, based on the planning book.

 

Supply and Demand Propagation

In Supply Network Planning, you use supply and demand propagation to implement continuous changes because of constraints and to find a feasible solution to fulfill the demands. Supply and Demand propagation doesn’t consider lot sizes.

 

Note − Supply and Demand Propagation in SNP is only used with time series live cache.

 

Executing Supply and Demand Propagation

To execute supply and demand propagation, you need to navigate to SAP Easy Access → Advanced Planning and Optimization → Supply Network Planning → Planning → Supply and Demand Propagation.

 

 

In SNP desktop, double-click the data view of the planning book.

 

 

Select APO Location Product and press ENTER. Next, double-click a location product in the list.

 

Enter a value of the key figure 9ATSML0SXI − fixed warehouse receipt.

 

Enter a value in the key figure 9ATSML0LFO − (forecast) in a later bucket.
