GR quantity more than production order quantity triggering cost difference

Question

Hi Gurus,
We have observed a scenario where the cost(price) dfference account getting hit whenever the GR quantity is greater than the production order total quantity. The dollars posted to this acount are directly propotional to the difference between the GR quantity and the production order quantity.
The total quantity specified in production order is 1 M2U and GR quantity is 1,000 M2U.Material price is $195.65.
Accounting Document;
Inventory account           - 195.65
Offset account                - 200.00
Cost difference account  -    4.35
If we do GR for less than or same quantity as in the production order, this account is not getting triggered.
Any idea what is causing this scenario? I really appreciate if you can share with any SAP note related to this.
Thanks,
Mano.

Hello Gurus,
One  more observation is,
The palnned costs and actual costs are always different when dealing huge quantities. But the cost difference account is only getting triggered if the actual quantity is  more than the palnned quantity.
And,
when the difference between atual quantity and palnned quantity is huge then
Planned costs are booked to the inventory account
Actual costs are booked to the prodcution cost account.
Significant cost variance is booked to the cost variance account.
When the difference between actual quantity is less than/equal to planned quantity is not so huge then
Actual costs are booked to the inventory account
Actual costs are booked to the prodcution cost account.
Is this a standard behaviour?
Thanks,
Mano.
