So all products needed for quality check should be defined in the quality control point with operation: receipts?

I did the screenshot using my products but quality check still won't show inside the purchase order receipt

You can have check on specific products, product categories or all receipts.
Checks are created when the operation is created. So it needs to be set up before you confirm the purchase order.

Got it thanks! But is there a way to choose a control point when receiving a product form purchase order?
