I don't want the "is free item" in purchase Invoice

When I purchase a certain quantity of items from a supplier the supplier offers me free items.
I want to include these free items in the PO and also in the Purchase receipt but I don’t want the free items to be included in the Purchase Invoice, how can I handle this? Please, anyone.

@Jalal

There is no option of selecting the free items at the PO and PR level.
You can directly deselect/select it at the PI level.

In case you have enabled a pricing rule, then the free item will get automatically selected.

Hope this reply solves your doubt.
Thank you
