Problem
The issue arises when a PO's date received is incorrect and does not match the invoice and receipt dates.
Solution
Change the date received on a purchase order that has already been marked as received
Go to the Documents section of the PO you need to edit.
Cancel either the receipt or the bill associated with the PO. It doesn't matter which one you choose. This action will change the PO's status to pending.
After canceling, click on Actions and select Edit.
In edit mode, you should be able to change quantities and amounts. If the date received is not editable, try canceling both the receipt and the bill.
If, after ensuring the PO is in pending status, you still face issues editing the date, double-check the permissions associated with your account. Some account roles may have restricted editing capabilities.
