German to English Bus/Financial Finance (general) Tax

In a text about a computer system for managing bank accounts:

Über Subsysteme -> Rechnungswesen -> Stammdaten -> Kontierung gelangt man in die Pflege der Kontierungen. Bei der Umsatzsteuer wird über die Preiskomponente das MWSt-Konto angesprochen. Bei der Vorsteuer geschieht dies über den Geschäftsfall.

I am really struggling with the second sentence as I can't seem to work out what "angesprochen" could mean in this context. Does it mean something like:

When calculating income tax, the VAT account falls under the price components? That's about as close as I've come to understanding it so any help would be very welcome!
