Configure the price adjustment base for installments
You can specify a minimum installment payment amount that determines which installment payment options are displayed to customers at checkout. You can also configure the ratio that determines the dominant item in the shopping cart; the installment payment options of this item are applied to the entire shopping cart.
Procedure
- Open WebSphere Commerce Developer and switch to the Enterprise Explorer view.
- Open the installments engine configuration XML file in an editor:
WCDE_INSTALL/xml/config/com.ibm.stdwip.commerce.installment/wc-component.xml/wc-component.xml
- Update the property value in each of the following code segments:
<_config:property name="minimumInstallmentAmount" value="100.00" />
<_config:property name="dominantCatalogEntryMinimumProductTotalRatio" value="0.5" />
- minimumInstallmentAmount
- A global property that prevents installment payment options which are lower than the specified value from being offered to customers at checkout. This value overrides any minimum installment payment amount specified in the Installments tool within the Management Center, except when the amount specified in the Management Center is higher than the amount specified in the wc-component.xml file.
- dominantCatalogEntryMinimumProductTotalRatio
- When you have multiple items in the shopping cart with different installment payment options, this property is checked to determine the dominant item in the shopping cart. For example, if the shopping cart contains an item that costs more than a certain percentage of the total price of the shopping cart, the payment options of this dominant item are used for the entire shopping cart. The default percentage is 50%. If the shopping cart does not contain a dominant item, a combination of each item's payment options is used.
- Save and close the file.
- Restart the WebSphere Commerce server.
- Deploy the configuration changes to the production environment.
