CAN ANYBODY REPLY TO THIS QUESTION :
Mike Keller did a period billing for WBS 2008044-MO & 2008052-MO Jan 2 through Feb 29.
The Invoices had to be cancelled because of the wrong Tax Code. Mike cannot perform another DP91 for the same period.
How does he create another invoice for the same Time Frame Jan 2 - Feb 29???
PLEASE RESPOND AS THIS IS URGENT.
