Adding Payment After order is placed

I have looked all through the forums, and tried unsuccessfully to Add a Payment to a test Order I placed using the PO or Check method of ordering.



Using version : 2.06



A little more info:



A customer places and order - chooses PO or Check in the payment option during check out. Order is processed, shipped etc… In the admin section I can change the Order to any I want, I know this, but I need to be able to Add a Payment and appropriate check info once the check is received. I cannot figure out how to accomplish this.



How do I add a payment, of any kind to an order that was placed, and fulfilled after order creation?



Thanks,

EagleRose

Anyone have any ideas on how to solve this?
