Different users can be assigned different authorisation levels for the forecast system in Aiolos Forecast Studio. Program users are set up in FILE – Modify users. The highest authorisation level is assigned to the role of “Administrator”. A user who is to work in CONFIG will need this role. In addition there are several levels of authorisation for different types of user. A user with the role “Limited” can only see those series that are part of a given selection. In this way you can conceal parts of the series tree from certain users. A user with the role “Guest” can only see forecasts and history but not produce forecasts or make other changes.
