(ID# 26) Use this A/P option in Options Configuration to indicate whether or not you can post to a closed A/P period, and if you can, for how long.
Valid values are 0-28. A value of 0 (zero) indicates that this feature is not used. A value of 1-28 indicates the last day of the current month for which you can post transactions to the previous month.
For example, if today's date is the 10th of the current month, and your "Accounts Payable Closed Posting Day'" is 10, you can still post transactions for last month (i.e. you can still enter transactions with a voucher date of last month). However, if today's date is the 11th or greater, and you try to add a transaction with a voucher date of last month, you get a warning that you're trying to post to a closed period. However, if you have security bit 368, you can simply click OK to bypass the warning. If you don't have security bit 368, you would not be able to override the warning.
