Creating an external price rule that references an ILOG JRules ruleset

If your site is integrated with IBM WebSphere ILOG JRules BRMS for pricing, you can create price rules in Management Center that reference ILOG JRules rulesets. The price rule that you create, which is called an external price rule, acts as a "wrapper" for the ILOG JRules ruleset. This price rule allows you to use the ILOG JRules ruleset for pricing on HCL Commerce stores.

Before you begin

Your site must be integrated with WebSphere ILOG JRules.
The ILOG JRules ruleset that you want to reference must:
- Use the predefined vocabulary that is compatible with HCL Commerce.
- Be deployed to the WebSphere ILOG JRules Rule Execution Server so that you can retrieve it in Management Center.

About this task

Management Center supports two ways you can use an ILOG JRules ruleset for pricing on an HCL Commerce store. In both cases, you must first create the external price rule that references the ILOG JRules ruleset. Then, you can either:

Assign the external price rule directly to a contract, as you would with any other HCL Commerce price rule. In this case, the pricing instructions are coming only from the ILOG JRules ruleset.
Nest the external price rule in an HCL Commerce price rule by using the Apply Nested Price Rule action. Do so only if you want to combine HCL Commerce pricing elements, such as actions and conditions, with the ILOG JRules ruleset in the same price rule. Then, you can assign the HCL Commerce price rule to a contract. The following price rule is an example of this usage. Here, the HCL Commerce pricing element is the Get Price from Price List action. This action passes a price to the nested external price rule that references the ILOG JRules ruleset:

The following procedure is applicable to both of these usages.

Procedure

Open Management Center tools and from the hamburger menu, click Manage Accounts > Catalog Filter and Pricing .
Open Management Center tools and from the left navigation menu, click Business tools > Customer Management > Price Lists.
From the toolbar, click the arrow on the right side of Create New; then select External Price Rule.

Set the price rule properties:

Property	Description
Name	Type a name for this price rule. This name displays beneath the price rule in the Price Rules - List page.
Description	Enter text that explains what the price rule is intended to do.
External price rule	Specify the ILOG JRules ruleset that you want to reference in this price rule. Here are two ways you can do specify this ruleset: Option 1: To get a list of all available ILOG JRules rulesets, type an asterisk (*) in the field above the External price rule table, and then click Find and Add. If you get more than one result, drag the correct ruleset from the utilities view into the External price rule table. Option 2: Type the ruleset path in the field above the External price rule table. The format of an ILOG JRules ruleset path is: `/RuleApp name/version/ruleset name/version` Where `RuleApp name` and `ruleset name` can be composed of digits, letters, and underscores. Both names are mandatory. `version` is optional. If the version is not specified, it is the latest activated version of the RuleApp or ruleset. `version` is equivalent to: `number.number` Examples of valid ruleset paths are: /rule8_8app/6_ruleset_6/1.0 /rule8_8app/1.0/6_ruleset_6 /rule8_8app/6_ruleset_6 /rule8_8app/1.0/6_ruleset_6/1.0 Click Find and Add. If you get more than one result, drag the correct ruleset from the utilities view into the External price rule table.

Save and close the price rule.

What to do next

You can either:

Assign the external price rule directly to a contract, as you would with any other HCL Commerce price rule.
Nest the external price rule in an HCL Commerce price rule by using the Apply Nested Price Rule action, as illustrated in the example in the introduction to this procedure.
