Production Planning for Process Industry 
Production planning for the process industry includes new master data and optimization functions.
You can also precisely model the production restrictions for consecutive operations in a simple manner. With resource networks, you define the permitted links between resources in a plant. In doing so, you define the actual production flow between the individual resources. This forms the basis for the creation of a feasible production plan.
When the material flow is defined in the recipe within the SAP ERP system and transferred to SAP APO, this data is created as a product storage definition in SAP APO. Using these you can assign multiple container resources to a product belonging to a production source of supply, such as PPM or PDS.
In planning with container resources, it is possible to take the maximum capacity of the container resource into account. This new container planning is based on optimization. The optimization function can process all requirements, sourcing alternatives, resource networks, and product storage definitions of the products to be planned. Optimization creates a feasible production plan on the basis of this data and creates new orders. For more information, see SAP Notes 1171154 and 1155421.
Features
The following master data has been enhanced:
Resource Network
The master data in PP/DS has been enhanced by the addition of resource networks; you can create, change, display, or delete these. To access resource networks, in the SAP Easy Access menu, choose 
Advanced Planning and Optimization
Master Data Resource Resource Network 
. Alternately, use the /SAPAPO/RESNET transaction directly. For more information, see Resource
Network.
A new BAdI for resource networks, /SAPAPO/BADI_RESNET, is also available. You can use this BAdI to implement customer-specific changes for resource networks.
Product Storage Definition
With the product storage definition, you can assign the components of a production source of supply to one or more container resources. It is possible to assign several alternative resources. You can create the product storage definition manually or have this done automatically at the time of the CIF transfer of the PPM or PDS data.
To access product storage definitions, in the SAP Easy Access menu, choose Advanced Planning and Optimization Master Data Product Storage Definition Product Storage Definition
. Alternately, use the transaction /SAPAPO/STORDEF. For more information, see Product Storage Definition.
A new BAdI for product storage definition, /SAPAPO/BADI_PSD_DEFS, has also been introduced. This BAdI enables you to change the product storage definition if required.
Product Master
In the Product Master, the following version-dependent fields are now available on the Demand tab screen under Pegging:
Resource Network Name: In this field, you specify the resource network with which the product can be associated.
Resource Network Strategy: In this field, you specify whether pegging must take account of the assigned resource network.
Container Resource Strategy: In this field, you specify whether pegging must take account of container resources.
For more information, see Maintaining Settings in Product Master Data.
Resource Master
The storage characteristics of a resource have an additional field, Allow Multiple Products, which determines whether different products can occupy the resource simultaneously or not.
Resources are also enhanced such that you can maintain storage characteristics for single-activity resources also.
