For Swedish tax reporting the house (you) are supposed to generate "Kontrolluppgifter" which are called KU's. Each KU has specific settings that has to be made. Some are based on transactions and some are based on holdings or values for certain points in time.
In order for a KU to be generated correctly the financial instruments in BFS has to be labelled correctly so it is very important that your database is clean from any erroneous data.
Once you log on to the application you should click on the menu item Tax Reporting Tool which will display the following screen.
The view will show the KU's that are supported by the application. Click on the documentation for each KU below.
