All databases have three default data levels: Actual, Budget and Forecast. However, data levels can be added to achieve more "layers" of data. An example of using multiple data levels is Budgeting, where each scenario can be on its own data level. These scenarios can be looked at individually or compared all at once on Navita reports and input forms.
Data levels are located under Administration -> Data levels
To add a new data level, click Add. Afterwards you can write a name and lock the data level for a desired time period. Save changes by clicking Save at the right end of the box.
Edit existing data levels by clicking Edit in the actions column. You can edit the name and locking information. Save changes by clicking Save at the right end of the box.
