From what I can tell of the discount system you will need to do the following before saving the rule. As you can see it works by searching for any cart product with a specific SKU.

$sku = 'ABCD';            // Put your product SKU here
$found = Mage::getModel('salesrule/rule_condition_product_found')
         ->setType('salesrule/rule_condition_product_found')
         ->setValue(1)           // 1 == FOUND
         ->setAggregator('all'); // match ALL conditions
$model->getConditions()->addCondition($found);
$skuCond = Mage::getModel('salesrule/rule_condition_product')
           ->setType('salesrule/rule_condition_product')
           ->setAttribute('sku')
           ->setOperator('==')
           ->setValue($sku);
$found->addCondition($skuCond);

Jitendra  2010-10-28 12:54:42

Jitendra  2010-10-28 12:55:43
please help me this code is not working or i am not applying it properly
Jitendra  2010-10-28 14:41:34
I made a mistake when tidying up the snippet. It seems the order each condition is added in has an effect.
clockworkgeek  2010-10-28 15:11:21
can u please elaborate more on your last comment.
Jitendra  2010-10-29 05:01:53
My answer has been corrected so it should work better. Please try it again.
clockworkgeek  2010-10-29 11:25:12

Jitendra  2010-10-29 11:38:59

@eyelidlessness FYI i have put this answer my self please read the answer properly..

@Jitendra, Stack Overflow is a valuable resource partly because its users gain reputation for good questions and answers. It provides a direct way for questioners to accept answers for this reason: the person who provided you the correct answer is rewarded by gaining reputation points and becomes better able to participate in the site by doing so. Taking the answers provided by others and posting it yourself undermines the value of SO for its users.
eyelidlessness  2010-10-30 07:53:20
@eyelidlessness:Please read the conversation below u'll understand what is going on,and the for the award concern i am ready to accept the question but where is the chekbox to accept it i cant see it after the any answer..
Jitendra  2010-10-30 08:25:54
@clockworkgeek please say something
Jitendra  2010-10-30 08:26:36
@eyelidlessness - It seems Jitendra has superseded my suggestion with a better answer. Twice! Thank you for your concern. Still, I had to correct my own snippet in case of another visitor attempting to use it.

thanks, Jitendra

Jitendra  2010-10-29 08:00:07
It sounds like you need to use "catalogrule" instead of "salesrule".
clockworkgeek  2010-10-29 11:32:13
is it possible in salesrule..?
Jitendra  2010-10-29 11:40:29
Using salesrule automatically adds a line in the totals section. If you want to avoid that entirely and just reduce the price of a product directly then consider overriding it's price model. The price model is particular to a product type and has the method `getPrice()` called. Apply your reduction there instead of messing with discounts and your customers will see it's effects everywhere.
clockworkgeek  2010-10-29 11:56:42
You are absolutely right but the requirement is that i have to do so using coupon code generation because the definition of
Jitendra  2010-10-29 12:38:38
my assignment is such like this customer can be able to get the discount for particular product using discount code only.
Jitendra  2010-10-29 12:40:48
@clockworkgeek Thanks for your answer but this is possible in shopping cart price rule see mynew code below i have done it.you just have to apply condition in the actions tab of shopping cart price rule.
