Payable Check will not Post

I am using GP2010

I have a payable batch with just one check. The check printed out without any problem. The check is not apply to any invoice. I want to just post the check. GP is not allowing me to just post the check. The batch status is available. There is nothing in batch recovery. Check the SY00500, SY00800 and SY00801 tables nothing there. Not sure what is the problem. I can edit the check if I want but can not post the check.

Any Suggestions?

Thanks,

Kevin
