Variance in COPA based on Quantity sold

Dear Experts,

I have a question in COPA. When I settle the production order, entire variance goes to COPA irrespective of quantity sold. However according to me it is not correct. Below is the example:

Produced 100 Pcs with standard cost of 10000 INR (Actual Cost 12000 INR)

Variance - 2000 INR

Qty Sold - 75 Pcs

Variance as per me should be 2000/100*75 = 1500 INR

However in COPA I am getting 2000 INR. since I am subtracting my variance with the sales, it seems to be undervaluing my profit as my qty sold is 75 pcs, however variance is for 100 Pcs.

Is there any configuration required to correct the same.

Thanks in advance for your help !!

Regards,
