What causes this issue?

In purchasing, different units of measure have been entered for
discounted goods, i.e. in the fields for purchase order quantity, free
goods quantity and additional quantity.
This situation is not practical in the purchase order since the
original purchase order quantity would have to be split up into
different units of quantity so that the free goods quantity can be
deducted from the original purchase order quantity.
The same checks are carried out for inclusive free goods
quantity in sales

System Response

The free goods cannot be saved.

How to fix this error?

The quantity units must be the same.
