I need to have different order total discount rates in % for each customers. The default discount is 10% for all users and it need to be override for certain users too. i.e administrator can set the different discounts such as 12% for user1 and 15% discount for user2 etc on a specific interval (between valid from and to dates). Is it possible using rules or custom module?
Please help.
Yes, Rajeesh, anything is possible with Rules. : P
In this case, I'd recommend something like a discount percentage field on user profiles that defaults to 10% and is only visible to administrators who can then override the field value on a user-by-user basis. Your product pricing rule can then look for this field to have a value on the order's user (i.e. use commerce-line-item:commerce-order:owner as the token, not the site:current-user) and then apply it as a discount using the appropriate line item action.
Can you try using commerce discount module which supports dates as well as users... See screenshot below of Create Discount Form..
Provides a user-friendly UI for managing discounts. The discounts are exportable entities based on which the discount rules are generated.
Contains two submodules:
commerce_discount_date: Allows limiting discount validity by date, requires the Date module. commerce_discount_usage: Allows limiting discount validity by number of uses (as of alpha1, still needs work!).
Thanks @Ryan Szrama, the product pricing rule and user account new field 'field_vip_disc_perc' worked for me. Now I can override the discount field integer value of each user and gets it deducted from the order total as discount percentage value. In pricing rule event 'Calculating the sell price of a product' I added the action "Multiply the unit price by some amount" for Data Selector 'commerce_line_item' with the Amount 'field-vip-disc-perc'. To get the discount percentage deducted from order total, I added the PHP evaluation return value, $value = 1-($value/100); return $value; which is applied to the Price component type Discount.
