Proof of Invoice printing
The invoice were not printing due to some out put issue. Once the out put issue is solved, the user is not sure how many invoices were not printed in the past two months (From April 01 to May 31).
How do weknow that for how many customers the invoices were not printed so that the action can be taken before the customer complains.
I have tried with VF31 but the user is not satisfied. The user is telling that by spool request it can be found.
Please guide how we can ensure that the invoices were not printed for some customers.
