Spread Discount expected behaviour

Hi,

Please find the test case below,

Product A: 550 (Price Overide: 550)
Product B: 45308 (DIS % :10)
Product C: 3481 (Dis Amt: 550)
Product 234 - NO DISCOUNT APPLIED
Product E: 1 - NO DISCOUNT APPLIED
Product F: NULL
Product G: NULL

Later I applied Spread Discount on all Items as 25% and the result was:

1) Price override Fields go blank.
2) Discount % Fields go blank.
3) Discount Amt field is populated with amount based on new calculation as per spread disc.

And finally this is how extended prices looked:

Product A: 566 (Price Overide goes blank and Dis Amt is set to 188.75)
Product B: 37757.25 (DIS % is blank and Dis Amt is set to 12585.75)
