What is the meaning of the symbols regarding the invoice status and when is which status displayed?
The invoice status is position based and that means that only when a position has been fully invoiced the status will be shown as fully invoices aswell.
There are 3 different invoice sttatus:
1. The order has only 1 position which is not or only partially invoices --> invoice status = "not invoiced" (symbol: ---)
2. The order has more than 1 position, where 1 position has been fully invoiced but the other positions are not at all or only partially invoiced --> invoice status = "partially invoiced" (symbol: half green circle)
3. The order has more than 1 position and all of them are fully invoiced --> invoice status = "fully invoiced" (symbol: full green circle)
