What's the days per posting cycle?

The Days per Posting Cycle setting lets you process the transactions you're posting in smaller groups to ensure that you don't run out of rollback space during posting.

For example, if your accounting period is 30 days and you set this value to 30, the posting process uses only one cycle. If your accounting period is 30 days and you set this value to 17, the posting process uses two cycles. Best practice is to set this field to a value less than the number of days in your accounting period.
