Wrong check date

Hello,
i have a situation on the payment entry. our finance made the payment and sent out the check and posted the payment. now, they found they put the wrong date. the apply date must be in july but they put in June. how can we fix that. if we void the payment and recreate the new one, can we keep the same sequence for the check?

also, when i try the post, i got the following popup

thanks,

Eddy
