Purchase Order Supplier not filtering on Item Code


When creating a Purchase Order, setting the Supplier field creates a filter on the Item Code that does not seem to work.

I have a supplier called “Test Supplier” and have added it to an item.

The filer on Item Code Is “Supplier = Test Supplier, Allow Purchase = Yes, Has Variants = No”.
Despite this filter, every item is being shown instead of just the item with Test Supplier.

If there is a solution, please let me know; otherwise, this might be a bug.

Note: Material Requests are not going to be used for this company, we just need the filter to work directly on the PO.

Thank you
