Data Deployment Error: DUPLICATE_VALUE:This price definition already exists in this price book

When doing a data deployment, Salesforce may return the following error: 

“DUPLICATE_VALUE:This price definition already exists in this price book”

This error occurs when multi-currency is enabled and there are multiple ISO codes in the source org, but there are no matching currency ISO codes in the destination org. 

To fix this issue, make sure multi-currency is turned on in your destination organization, and the currency ISO codes match in your source and destination organizations.

How did we do?
