Can we Access Multi-Currency Values from Custom Setting using Apex Trigger

Question

I have a Standard Object "Opportunity" I want to access a custom-setting with multiple currency

I have multi-currency enabled in my org.

Generally a custom setting can be accessed like follows

Using Hierarchy :

Custom_Setting_Name__c mysetting = Custom_Setting_Name__c.getInstance(); 

Using List :

CustomSettingName__c mySetting = CustomSettingName.getValues('SomeValue');

or

CustomSettingName__c.getAll().values();

I would like to know if we can access the multi-currency values ( Type : Picklist ) the same way as above or is there a special way of handling multi-currency in force.com.

Any head-up will be much appreciated.

You only need to define the currency iso code on your account records. Then once you create a new opportunity for a particular account, it will default the currency automatically from your account.

To define the currency automatically on the account. I would create a custom setting list with the country as the Name and a text field for the IsoCode. Then with a trigger before insert, set the CurrencyIsoCode based on the custom setting.

account.CurrencyIsoCode = CountryCurrency__c.get(account.BillingCountry).CurrencyIsoCode__c;
