I need the global price list from Oracle from 2019 and the following years. It needs to be understood how an IT System integrator buys from a distributor and how the terms with the distributor also determines the profilt of the system integrator. Also someone would need to look at specific data of profit calculations to determine, whether the calculation was correct or to what extent incorrect. Profit calculation must be corrected then.
