Corporate Income Tax Calculation (DDPO/DDD settings) 
It need to be set some registers first to calculate corporate income tax / DDD:
Users set registers before the start calculating corporate income tax. This should be done in conjunction with the chart of accounts used and the entries in it. General setup of registers is not possible because users use different chart of accounts and different ways of posting and elimination of tax entries (eg. nondeductible items or partially recognized values, posting the differences in transfer prices, etc.).
