Field help (KAUTINV) 

This field is displayed only when the KPO activity code is active.

This field is used to specify if the invoice type results from the self-invoicing process. In this case, the invoices of this type are not exported to the SAFT. The document must be entered internally but the digital signature is performed by the client software.
Invoices, whose Auto-invoice indicator is active, are always manual type invoices (these invoices must not be processed by the automatic invoice functions). This limit aside, this type of invoice can be processed as an invoice for a direct invoice order, based on the delivery information and other.
