Create a new draft supplier invoice.
Consider converting a Purchase Order to a Draft Supplier InvoiceIf you are working with purchase orders in Rackbeat, then you should convert purchase order to supplier invoice instead of creating a supplier invoice from scratch. By using the convert endpoint a link between the purchase order and the supplier invoice will be created.
If you would line the supplier invoice to be created as a draft during the conversion, then include
book=falsein your request.
