To open a new year, the previous year must be closed, i.e. it must have at least the status "Definite".
In addition, when you open a new year, a new time axis is created so that the data is saved over the correct time period.
When opening AbaSalary, you can select the year in which you want to work.
In the AbaSalary app, only 2 years can be opened at the same time. However, you still have access to the data of the closed previous years, such as the employee data or the OASI wage statement, but you can no longer change them because the years are closed and locked.
