I’m confused by the behavior of the “Invoice Status” of the Sales Orders.
After invoicing, the sales orders usually get the invoice status “Nothing to Invoice”. But sometimes they receive status “Fully Invoiced”. I cannot figure out the reason why this happens. There has to be a logical explanation however...
Business context is a service process with products defined as “services” and invoicing policy according to “Delivered quantities”. Track service is "Manually set quantities on order” except for one product/service with Track service as "Create a task and track hours"
