Delete a receipt of Transfer Order?

Hi!

I have a major problem today... For the first of july, we updated our cost prices.

Some people tried to make receipt for transfer order entry and the system did not understand the change of price between the time we placed the transfer order and the time where the receipt has been made...

So, those transactions are not posted, because they don't balance.

I need help, cause I can't delete the transfer order receipt in epicor. It seems to be in a special state....
