In my thesis I present the features of the business intelligence platform used for the implementation of cost allocation and the reasons behind this particular choice for the solution. Furthermore, I demonstrate the common architecture and its central application, which is built in Oracle Essbase. I will also go through some use cases regarding the subject. I introduce the Microsoft Excel workbook used to implement the cost allocation automatization and the generation of allocating statements with the explanation of the applied commands. The testing of the scripts made is also mentioned. Moreover, I explain the integration of the complete Oracle Essbase applications to a different system. I go in depth in the designing of the whole process and its components explaining the choices in the engeneering. I adumbrate the logic and showcase the composition of the components. Finally, I rate the quality of the applications, summarize the experience gained and mention some possible developments for the future.
