Sometimes you submit the sales order and then forget to delivery and invoice. This can not be filtered simply by clicking the overdue button, like all the other status settings.
In order to find those invoices with this setting, you need to creater a filer:
Status – not equals – draft
Status – not equals – cancelled
Status – not equals – completed
Delivery – < – 100%
Date – < – todays date
This will filter out all items and should almost all be “overdue” sales orders
