New Calculator are fit into existing ATG
commerce pricing architecture ,In ATG four
the calculator are present:
1) atg.commerce.pricing.ItemPricingCalculator
2)
atg.commerce.princing.OrderPricingCalculator
3)
atg.commerce.pricing.ShippingPricingCalculator
4)
atg.commerce.pricing.TaxpricingCaliculator.
For Example: if you want to create new item
pricing, implement
ItemPricingCalulcator.
Condition:- assume you have identified a need
for a calculator that sets an item’s price to half its current price plus one
The existing ATG Commerce tools include an
ItemDiscountCalculator that
discounts items. It can give a percent off a price or an amount off, or it can
set an item’s price to a fixed amount. None of these three options, however,
easily gives a “half off plus one” discount. To achieve that result, you would
have to use two different discounts: one to give 50 percent off, and another to
add 1 to that total. A better alternative would be to create a new calculator
that discounts an item’s price to half its current price plus one.
Step 1:-Create a new Component under
atg/commerce/pricing/
HalfPlusOneDiscountCalculator.properies
$class=com.corbus.commerce.pricing.
HalfPlusOneDiscountCalculator
Step:
create new class “
HalfPlusOneDiscountCalculator.java” and extends ItemDiscountCalculator
and override findAdjustedPrice() method.
package
com.corbuse.commerce.pricing;
import java.util.List;
import java.util.Locale;
import java.util.Map;
import
atg.commerce.order.Order;
import
atg.commerce.pricing.DetailedItemPriceInfo;
import
atg.commerce.pricing.ItemDiscountCalculator;
import
atg.commerce.pricing.PricingException;
import
atg.repository.RepositoryItem;
public class
HalfPlusOneItemDiscountCalculator extends ItemDiscountCalculator {
/**
* Override the
findAdjustedPrice to allow us to always compute the
* new price of the
input DetailedItemPriceInfo to be half its current
* price plus one.
* @param
pDetailedItemPriceInfo the details on the item being priced
* @param
pPriceQuotes list of itemPriceInfo
* @param pItems
list of commerceItems
* @param
pPricingModel pricing model being used to calculate price
* @param pProfile
users profile, not used here
* @param pLocale
users locale, not used here
* @param pOrder
users order, not used here
* @param
pExtraParameters map of extra params, not used here
* @return a value
of type 'double'
* @exception
PricingException if an error occurs
*/
public double
findAdjustedPrice(DetailedItemPriceInfo pDetailedItemPriceInfo,
List
pPriceQuotes,
List pItems,
RepositoryItem
pPricingModel,
RepositoryItem
pProfile,
Locale pLocale,
Order pOrder,
Map
pExtraParameters) throws PricingException {
// current
price of an item
double
currentAmount = pDetailedItemPriceInfo.getAmount();
return (
currentAmount / 2) + 1;
} // end findAdjustedPrice
}
Step 2:
Update the pricingModels Repository,
Note:-you
can check the repository http://localhost:8080/dyn/admin/nucleus/atg/commerce/catalog/ProductCatalog/?propertyName=definitionFiles
Create
a new pricingModel.xml under the atg/commerce/pricing/pricingMpdel.xml

</property>
</table>
</item-descriptor>
</gsa-template>
Step 3: now Create new promotion
1) Open http:localhost:8080/dyn/admin/
2) Open ATG Control Center Admistrator.
3) Open Pricing tab,under pricing click on promotions .
4) Create new promotions (Note: when you will create on new
promotions you can see Custom item type promotion name).
5) When you will create new Promotion ,you can check the date base
tables also(dcs_promotion, dcs_discount_promo)
6) Check below the screen shot:
7) You can check the way
ItemPricingCalculator oney way you will added new item into card or
