How to update campaign pricing discount through coding

Hi ,

I have a requirement where I need to maintain campaign Discount through coding.

Generally , we create the condition record by clicking on 'New' button on Discount assignment block . Then its shows pop-up to choose the Condition type combination. When we click on it , it redirects to Edit list View component and we maintain there only.

But here I need to maintain directly Discount assignment button through coding.

Please help me out here.

Thanks,

Satya
