The notified quantity exceeds the ordered quantity &1 &2

What causes this issue?

The total notified quantity is greater than the ordered quantity
including the overdelivery tolerance. If you do not increase the ordered
quantity accordingly in this case, a goods receipt (GR) in the amount of
the notified quantity is not possible. This is because the GR is limited
to the ordered quantity plus overdelivery tolerance.

How to fix this error?

You must reduce the notified quantity, so that it does not exceed the
ordered quantity. Alternatively, you must increase the ordered quantity
in the purchase order after posting the inbound delivery.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
