SAP BW: calculating reject costs in production

Until now, the customer evaluated rejects using uniform costs; i.e. one reject part causes costs regardless of when the reject occurred during the production process. The new data model uses existing data for reject quantities in production and enriches these with data from the product cost analysis. Here, planning data from the material cost calculation is extracted from the ERP system with a quantity structure. In the material calculation with quantity structure, planned costs are recorded with batch sizes and assigned to individual work steps. This enables an evaluation of reject costs that can be allocated to causes.
