APO Model Maintenance
The Supply Chain Engineer (SCE) is your tool for creating and maintaining supply chain network models. The network model represents a specific supply chain and consists of individual nodes and links. A node denotes to a location or business entity in SAP APO. The connections between the locations are the transportation lanes. The locations include the following:
Production plant
Distribution center
Customer
Supplier
The supply chain model also enables you to keep track of other supply chain elements, in addition to locations and transportation lanes, such as products, production process models (PPMs), and the following resources:
Handling
Production
Storage
Transportation
A model can have different planning versions. This gives you the option of creating different models, each with different versions for simulation purposes.
The SCE modeling screen is divided into two areas:
The upper part of the screen provides the view of your model.
The lower part shows you a hierarchical display of the objects in your work area.
Prerequisites
Create master data (model-independent data):
Locations
Location products (define the global and location-specific data for the product)
Resources
Production process models (PPMs)
Means of transport (APO Customizing)
Process
Before starting, you must create master data for locations, location products, resources, and other model-independent elements. You create and maintain the supply chain model in the SCE by placing the locations on the map and using transportation lanes to connect the locations together and form a network. The direction of the lanes shows the direction of the product transportation flow. To assign the products to the locations, simply use the drag and drop function. You must also assign a quota arrangement to your products to specify which percentage of the product quantity is to be transported to other locations in the chain.
