This change prevents inventory records from linking a product to the wrong batch or lot. By blocking these inconsistent records, stock availability searches become more reliable and businesses avoid confusing or incorrect inventory results.

It is possible (and actually quite easy) to generate a quant where the lot's product does not match the quant's own product.
That is however a severe incoherence and may lead to bizare effects when searching for available quants.
It's probably much better to forbid that.

The purchase app's filter for incoming shipments to invoice has been corrected after an obsolete invoicing option was removed. This prevents users from seeing or relying on a filter tied to a process that no longer exists, reducing confusion during purchasing and invoicing workflows.

The invoicing method to create an invoice on incoming shipment has
been removed in 9.0
