Configuring a rule (optional)

Rules that you configure in a Design Center resource set can be uploaded to Composition Center and shared by multiple business users and re-used in any number of document definitions. You can use scripting functions to make the rules more flexible and complex. For example, ODBC related scripting functions or Execute to call an external rule engine.

Example 6

A rule configured in Design Center

The following rule can be used to determine which texts and images to include in a letter intended for younger customers.

if ($category = "YOUNG")
   return "true";
   else
   return "false";

 

Notes about rules configured in Design Center

•	The resource set containing the rule resources must be connected to the Message configuration in the Project.

•	The rule statement is not visible in Composition Center. You should therefore give the rules descriptive names that inform the users of when to use a specific rule.

Exporting and uploading rules

When you export the Project, rule resource files are created. You must inform the Composition Center users where the rule files are stored.

Note:

You should not create rule files by using the Extract To File command in the resource set.

To configure a rule

1	In Design Center, open the resource set.

2	Right-click in the resource set and select New > Rule.

3	Give the new rule resource a descriptive name.

4	In the resource set, double-click the rule resource.

5	In the Rule editor, replace MyEvalFunc with a unique name for the rule function.

Note:

Do not use white spaces in the function name.

6	Enter the rule function in the rule view.

7	Click Check Syntax.

8	Save the rule function and close the Rule Editor.
