Return order Discount price is not divide by return Quantity.

Dear friends I have a problem,

I create sales invoice with fix discount amount. It’s means discount given by invoice header level. Assume Invoice contain,

Item A - 3 qty . and header level condition type discount 300 USD.

After sales 1 qty item return then,

we will create Return sales order reference by the above created invoice.

But Item A Return Qty 1 also getting item level discount value 300 USD.

This is wrong configuration of the discount condition type.

Correct discount value in sales return order should be 300USD / 3 *1 = 100USD.

Please let me know what is correct configuration predict the above result. I attached my condition configuration in V/06 .dis-condtion.jpg
