P42101 - CSS - Free Goods is geting cancelled when I enter Reason Code

Hi,

I created an Order with Advanced Pricing set up, that creates a Free Goods line.

Steps:

1. Entered Sales Header

2. Enter Sales Detail with Unit Price overriden. Result: Free Goods line is created

3. Go back to same Detail line and enter Reason Code '01' and Row Exit - (Row Exited & changed Async). When I click on Free Goods Tab, Free Goods line disappears. 

My client doesn’t want this feature of deleting the Free Goods for any minor changes on the Order detail line.

Could you please suggest if there is an alternative to stop this feature?
