The DataCategory dimension stores Origination Years for Tax Losses and Credits in the TaxLossCreditTotal hierarchy.
By default, the system provides 20 Origination Years. The top year in the hierarchy is the oldest and the bottom year is the current year.
You can add Origination Years if needed by creating new members.
During the Rollover process from a prior period, the Current Year rolls over to the Current Year -1, Current Year -1 rolls over to Current Year -2, and so on.
