This is our second month of having tax books set up. We started them in August, ran initial mass copy for all, ran depreciation, and closed for August. 

Now for September close, when we try to run the periodic mass copy process (through scheduled process, manage all books, or depreciation infotile) the corporate book period is still blank. Does the initial mass copy need to be run every month?
