Policy Xpress › How to Create a Policy › Advanced

Advanced

Policy Xpress allows for many configuration variations and also interacts with external components. Due to this flexibility, errors may occur that are not necessarily bugs, such as an incorrectly configured data source, a missing value returned from a dynamic data element, or an endpoint which is not responding.

Usually when an error occurs, the system will stop the calculation of policies for the current step. However, you can change the default error response, based on the error category. For example, if you have a policy that is non-critical, you can define that the processing should continue in the event of an error.

The Advanced tab allows you to change the default error responses if necessary.

Note: We recommend that these error responses be left to their defaults, but for advanced use cases, these settings can be changed per policy. For example, if you have a policy that is non-critical, you can define that processing should continue even if the policy failed.

The following error categories can be configured on the tab:

• Validation—caused by providing incorrect information to a plug-in. This type of error is reported before the action is attempted.
• Environment—caused by problems in the environment, such as a failing database server for the SQL plug-in.
• Allowed—a non-critical error. The default behavior for this error type is to continue processing the request, such as when sending an email fails.

For each of the previous errors, the following options can be set:

• Fail event—stops the current action. This is the default for most error types.
• Fail policy—stops the current policy and all actions associated with it. The rest of the policies continue.
• Ignore—logs any failure but does not stop the actions or policies.
