Hi Team
 
I have a line item Existing Product formated as a List of Products. The value is being picked from another module. I am creating a new line item New Product again formated as a List of Products. I need to have this list as a dynamic list where the value from the Existing Products is removed. Since Product lists is a flat list , I cant create a dependent drop down.  Any suggestion will be helpful.
 
As a work around am using conditional formating on the line and highlighting the same in red. 
 
Regards
