Use this screen to reverse, or void, standard bills that have already been posted.

You can also rebill the same transactions from the original invoice along with any new transactions that have been posted to Open Billing Detail. Note that this utility reverses or voids standard bills only; manually entered bills such as project product bills, customer product bills, milestone percent complete bills, or manual bills are not eligible. In addition, you cannot use this utility to reverse or void progress payment bills.

Use this screen whenever you need to create reversing bills for bills that have already been posted. Note, however, that if the Assign Bills to User Groups check box is selected on the Configure Billing Settings screen, you will not be able to reverse bills for projects that are assigned to a billing user group of which you are not a member.
