How to avoid POand REQ getting in to "Pre-Approved" status due to chnage of teh GL date at the time

Hi,

When a PO or a REQ is created in the previous month and approved in the current month (when the GL period for the previous month is closed) it ends up in "Pre-Approved" status. in our business it's a regulay issue. Approval of high value PO/REQ go to higher level of approvers n(Higher management) and get delayed in getting approved.

 When it's approved it will go to "Pre-Approved" status and the approver will esnd back teh document to the creater using "Send back to preparer" option. Then teh user need to change tehGL Date and submit it for approval which will go up again in the same hierarchy.
