Tax Periods
If the Create Entity Tax Periods parameter was set in the Conversion Parameters utility, the Tax Periods were created from the GL Periods during the conversion. However, if this parameter was not set, you must create Tax Periods manually within the application.
Create tax periods from the GL calendar. Otherwise, skip to Reporting Periods.
