The Production Process Model (PPM) defines the detailed information required for manufacturing a product. The PPM combines routing and the bill of materials (BOM) into one master data object. Each PPM includes one or more operations. Each operation, in turn, includes one or more Activities, for which materials, relationships and resources are maintained. The activities and resources defined in the PPM are assigned to costs that are used by the SNP Optimizer and for finite scheduling by Production Planning and Detailed Scheduling (PP/DS).

The PPM used for Supply Network Planning requires less information than the PPM for Production Planning and Detailed Scheduling (PP/DS) and for Capable to Match (CTM).

The following diagram depicts how the PPM is created. Firstly, you define operations. For each operation, you specify the activities associated with the operation. For each activity, you should define the materials (logical components, products), relationships (between the individual activities) and resources (modes and resources).
