If you are unsure if roll cost forward ran successfully, please raise a new case online and reference the title of this article. If you raised this request for us to run this manually for you then please reference the case number also.
We usually run roll cost forward manually for customers when a case request is raised as there have been issues automating the roll cost forward in the past, and this way we can control the process and make sure that it has ran.
With regards to how to check if roll cost forward has run, there isn't an explicit way that you can check this. It has to be done in the backend.
If you have access to a non-live regularly refreshed database, then you could run the query:
Select * from finance_control
This query may work in a local report in the admin tool but that would require some testing locally.
You'd be looking for the current start and current end year rows to see what period window they are saying that your system is in.
Implicitly, you will not see any issues with your payment and billing cycles. Mosaic will calculate those correctly come what may. But on the package screens the figures may not look accurately uplifted for their new year in places so that might be one of the giveaways.
If you are in any doubt, then please raise a new case with us as described above.
