Why do "Unknown" suppliers appear in the "Supplier Analysis" report?
The reasons for the appearance of Unknown suppliers in the report are:
the customer has some products not tied to specific suppliers;
products received from these suppliers are sold out. In this case, the FIFO algorithm binds the stocks of such products to an Unknown supplier.
