Translation of "Ermäßigt" should be changed

Wenn you make an order you will see in the summary of the process the german word "Ermäßigt".

I would like to change this into a better translation but I cannot find the file. This word is not in de-DE.com_hikashop.ini.
Could anybody give me a hint, were I will find this?

That word is indeed not in hikaShop so I don't know from where it comes on your website but not in HikaShop. Maybe another language file on your website or a translation override.

Thank you nicolas for your reply but I have fixed this Problem: The word "Ermäßigt (english: reduced") was the name of the Tax - Class, I created for a reduced 7% VAT in Germany.
