The following assumes that the invoice has not been exported.
Vouchered:
If the invoice was created from a Voucher, then the best approach is to:
- unapprove the AP Invoice
- then, delete the AP Invoice
- open the now cancelled Voucher
- click the Uncancel button
- make required changes, and reprocess
This will keep both documents in alignment and avoid potential confusion.
Not vouchered:
If the invoice was not created from a Voucher, then the best approach is to:
- create a new AP Invoice batch for the same period as the invoice
- use the "wbUtilityChangeBatchNoAPInvoice" Utility to move the invoice to the new batch
- use the "wbUtilityChangeAPInvoiceBatchDate" Utility to update the date of the new batch and the Year-Period of both the batch and the invoice
