we are briefly using 3WM and just found a blind spot. When the user creates PO, (s)he has to also approve any invoice disrepencies through the workflow but once the user is deleted (s)he can't do so as the invoice arrives sometimes a month later or in case of frame orders even later.
We set up a substitute once as a test, but that is only valid for approving purchase orders and doesnt help us with invoices.
How do you deal with this?
Thanks in advance for any tips
