Currently, based on the "Business rules for fixed asset determination" procurement setup, certain purchases can be automatically treated as fixed assets if the purchase price item exceeds a monetary threshold, ONLY if we use purchase order module.

If we use "Vendor invoice" directly, the system should also automatically trigger the checkbox “Create a new fixed asset” and fill in the fixed asset group based on the setup of the business rules. For the moment, this is not happening. In some scenarios, the customers receive an invoice directly, for which they do not have a purchase order.
In this case, when the invoice is created in D365, it is possible to add the lines directly in the invoice matching details screen, instead of first creating a PO to link with the invoice. After having added the lines to the invoice screen, we can further process the invoice.
So instead of adding the lines to a PO and have the business trigger there (which works in standard D365), we add the lines directly to the invoice and I would think that the business rules would be applied here as well since it is almost the same logic.

Thank you!
