Hi,
I wanna add exchange rate field to my custom entity but i don't know how i do that. Exchange rates exist in currency entity but i can not add them to any entity. For example, My base currency is Euro, I have USD exchange rate that equals 1.200000 and turkish lira that equals 0.88888888. I want to add USD exchange rate(1.200000) and turkish lira exchange rate(0.8888888) fields to my custom entity to show users all rates. How can I do that ? Please help me as soon as possible if you have any idea...
Thanks..
