Welcome to Community, Julia44. 

I recognize how relevant it is to you to generate a report in multicurrency. Currently, this option is unavailable in QuickBooks Online (QBO).  

At times, we roll out enhancements based on our customer's requests. That being said, I suggest sending a recommendation to our product developers. They'll review this idea and might consider updating it in the future.

Here's how:

1. Go to the Gear located at the top.
2. Under Profile, click Feedback.
3. Enter your recommendation and select Submit.
   
   

In the meantime, you'll want to continue using the detail reports to see the foreign currency. 

I've added these articles below to learn more about how multi-currency works in the program: 

• Enter and use your own exchange rates.
• Learn about exchange rates in QuickBooks Online.
