Reporting Currency Ledger Opening Balance Error

Hi,

We have an existing Primary Ledger in XX EUR Currency which is already Live in Production.

There is requirement to introduce a new Subledger level Reporting currency Ledger in USD. Hence, we defined Reporting Currency ledger XX EUR - RCS USD . Once the reporting currency ledger is configured, we run the process 'Create Opening Balance Journals in Reporting Currency ' . But it is ending with error 'GLMRC017: The EMU fixed rate relationship doesn't exist for primary currency EUR to reporting currency USD.'

Any pointer would be appreciated on how to populate the Opening balance after introducing New Reporting Currency Ledger in an existing Ledger.
