Input validation expected on Purchase Invoices

I accidentally made a purchase invoice with a due date prior to the invoice date. Manager allowed me to enter this information with no error or warning. Manager version 17.1.40. It would be helpful if Manager alerted to this problem when an invoice is entered. Thanks.

Generally Manager always allows you to enter anything (including invalid input). This is to get out of your way. Whatever you want to enter, Manager will let you do it.

When it comes to finding these errors, Manager will typically make it obvious you’ve done something incorrectly after you save the entry. In this case, you’ve entered wrong due date, you found out about it and fixed it.

Thanks for the reply. I understand your response, but I would still like to see some input validation. Yes, I can go back and fix it later, but that is more time consuming than preventing an invalid entry to begin with.
