Copying a JDE Sales Order fetches incorrect pricing history for discounts in new SO

Hi,

I created an SO with base price of 10 Euro which was called through advance pricing,

Then i added a discount of 10 Euro to the SO.

The resulting unit price was zero in the SO.

After saving the SO, I copied the SO.

The discount amount did not get reflected and the unit price was 10 Euro(same as base price) in the new SO.

For other SO, where the discount price is unequal to the Base price, this issue does not arise.

Only in case of Base price=Discount price, this issue arises.

Could anyone shed some light on this.
