This Master Thesis Project was developed within the ICT Department of a Multinational Company in the Food Industry. Following the implementation of a common Enterprise Resource Planning (ERP) system provided by SAP, processes have been standardized across the globe and the data flow has been made seamless. The importance of Supply Chain Management has been acknowledged by the Company, that invested in the development of a SAP module called SAP Advanced Planning and Optimization (APO) in order to manage its Supply Chain processes. Demand Planners have been provided with more advanced techniques to manage their day-to-day tasks. Nonetheless, in the case of flavour Production Sites, demand planning remains an issue because of several reasons linked both with the nature of business and to difficulties to gather information from participants in the Supply Chain.
