The Transaction Attributes criteria allows AP Posters and Administrators to change the Post Date and Fiscal Period when posting approved invoices. This way, you don't have to change the invoice status back to INUSE and go through the approval process again. Just check the Replace Existing Document Post Date, and then select your Post Date and Fiscal Period.
This criteria is available when the Allow users to modify Vendor Invoice post date during bulk posting process (unanet.financials.allow_vendor_invoice.modify_post_date) property is enabled.
Note: You cannot change the post date to a closed fiscal period unless you are an administrator. For AP Posters, fiscal periods are limited to open fiscal periods for the selected legal entity (or all open fiscal periods if "All Legal Entities" is selected).
