Real-time integration is not active for any valuations in company code &1

What causes this issue?

Parallel valuations are active in the real-time integration variant that
is assigned to company code &V1&. The relevant parallel valuation also
needs to be explicitly activated in the Customizing activity
<DS:TRAN.FCML4>Set Up Real-Time Integration for Parallel Cost of Goods
Manufactured</>. This condition has not been met for any parallel
valuations for company code &V1&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

In the Customizing activity <DS:TRAN.FCML4>Set Up Real-Time Integration
for Parallel Cost of Goods Manufactured</>, activate the real-time
integration with FI for at least one parallel valuation for company code
&V1&.
