To make a correction or void an open invoice that has already been posted to the General Ledger, select Accounts Payable > Invoice Entry > Un-Update Open Invoice menu.

1. For the selected A/P account, select the vendor and then select the invoice you want to unpost. You have the option of selecting only one invoice or Select All. Note: The line with the selected invoice will be blue once selected. Using the Ctrl/Shift keys allows you to select multiple invoices. See Multi-selection for more information on this function.
2. Once you have selected the invoices you would like to unpost, click on the Un-Update button. If an error condition exists, the invoice will not be un-updated.
3. The selected invoices are now unposted and can be edited through the Enter Invoices to Pay screen.

NOTES:

• An invoice will not be allowed to un-update if it has a cash account in the coding and the entry falls in a closed bank reconciliation period.
• If an invoice that has been through the routing/approvals process is un-updated, the routing path will re-populate in the "Routing Path Name" field on the "Approvals" tab.
