Period End / Year end holding before closing


Hi there,

I have recently joined a company which uses sage 100. They do not close accounts monthly and do it on yearly basis, which means anyone can post entries in July when we are in September. I used MS Dynamics 2012 in the past organization and it had a "hold" option for posting. So I complete my checklist every month and put a hold on that month so no one can post entry by mistake or intentionally. This way I can control my accounts and financials.

Is there any way I can achieve this in Sage 100. Please note that I can open any month any time if there needs to be any entry done in a specific month.

Thanks guys
