Year end problem - fiscal calendar not created for all acocunts

SUGGESTED

Hi,

My client is using Sage 300 2016. They did a year end about a month ago which ended with the following message (I see this in restart maintenance):

Create New Year processing did not complete.
Run the Create New Year program again in order to finish new year processing.
State: 9, Batch: 010655, Account: 520020100

They had not seen this message and carried on work. Now, when they post they get an error that the fiscal calendar for 2018 does not exist.

I run an integrity check with fix minor errors on and I got 131 accounts with the following error: Account xxxxxxxxxx has no fiscal summaries for at least the current year 2018.

Any ideas how to go about fixing this problem?

Thanks

Marios
