I have set line discount (sales) for a specific item to a specific customer for the period 01.01.2013 to 31.03.2013.
Discount % was 7.
Now for the same item and same customer I want to give 10% discount from 01.02.2013 to 28.2.2013.
And from March onward 7% will again come in to force.
When I set this system is not taking discount which is set for 01.02.2013 to 28.2.2013.
So how I can achieve this.?!
