Production Planning
In order to use planned order management, you must have already executed the production planning.
The SAP APO system generally works in conjunction with an OLTP System. An SAP Discrete Industries (DI) system is used as an OLTP system.
The OLTP system provides the SAP APO system with the necessary planning data, using the CIF.
The planning is done in the SAP APO system.
Planning in the SAP DI System
You use Integrated Product and Process Engineering (iPPE) in an SAP DI system (from release SAP DI 4.6B) and specify the required master data.
If you use repetitive manufacturing with iPPE, create the line structure, the process structure, and the product structure.
If you use shop-floor-oriented manufacturing in iPPE, create the process structure and the product structure. In this case, no connection to a line structure is maintained. The system uses the relationships defined in the process structure to determine the sequence in which the individual activities are to take place in shop-floor-oriented manufacturing.
You enter customer orders and planning requirements in the SAP DI system.
Transferring Data into the SAP APO System
You have created an integration model to ensure that the SAP DI system provides the SAP APO system with the necessary planning data using the CIF. To create an integration model, from the

.You transfer the iPPE data to the SAP APO system.
In repetitive manufacturing, a line resource is generated for each line in the SAP APO system, which you create in the SAP DI system. The line resource forms the foundation for production planning for takt-based flow manufacturing in the SAP APO system.
With shop-floor-orientated manufacturing, a resource (for example, a single activity resource) is generated for every iPPE production resource to which you have assigned an activity in the mode in the SAP APO system. This resource forms the planning foundation for shop-floor-oriented manufacturing in the SAP APO system.
In the SAP APO system, maintain the settings for Interactive Planning in PP/DS, for example, the factory calendar and propagation range.
You transfer the necessary transaction data, such as planned independent requirements, customer orders, stock.
You maintain the master data relevant for planning in the SAP APO system afterwards:
You specify in the product master, whether the planning should take place using single explosion of iPPE, or with matrix explosion.
If necessary, you maintain production rates, shift models, and break times for the resource.
Planning in the SAP APO System
Execute a planning run in SAP APO for the product being planned:
Individual Explosion for Non-configurable and Configurable Products
To determine the component requirements, you can specify that your iPPE model should be exploded individually in the planning run.
You can start the planning run from the product view, or from the product planning table, or execute it as background planning.
Matrix Explosion for Configurable Products
You start the model mix planning run, in order to execute planning for a planned version and a line structure. The SAP APO system uses model mix planning to generate planned orders for the sales orders, to determine the sequence of the planned orders on the production line, and to determine the start and end dates for the planned orders.
The planning of the components required for the orders is integrated in the planning run of Model Mix Planning. According to the setting in the product master for the product being planned, the SAP APO system determines the necessary components with the help of the planning matrix or through individual explosion of iPPE.
