Error handling in Bizweaver allows the designer/administrator to easily handle error conditions in a workflow. There are two levels of error handling: workflow level and step level. The configuration of these levels is described in the following sections.

Bizweaver error handling supports sending an email to designated persons when a problem is encountered. To do this at least one SMTP global connection is required. And in this connection a valid user must be defined using the “SMTP Credentials” option as shown below. This is a valid email user that can access the SMTP server and is used as the “From” user when an email is sent.

Error handling is enabled for a workflow by selecting the “Error Handling and Notifications” checkbox as shown here.

Step level error handling cannot be used unless this option is selected.

• Leave the “Continue on Error” and “Enable Notifications” checkboxes selected as shown.
  • These options only apply to Step-level reporting, but must be selected here to allow workflow level handling to function AND to be available for step-level reporting..
  • The section highlighted green is for information only in case you wish to create your own format.
• Select the desired SMTP connection from the drop-down list.
• Enter one or more email addresses for persons to be notified in the event of an error.
  • At least one recipient is required.
  • Separate multiple recipients with a semi-colon (user1@twbs.com;user2@twbs.com).
• Define the email Content.
  • A default email layout at the workflow level is provided as shown in the image above. It should be adequate for most installations.
  • Items in < … > are selected from the “Add Tags” drop-down list. This allows you to create your own message layout if you prefer.
  • The tag <STEPLEVELERRORINFO> is used to present the information from a step-level error. If step-level notification is enabled, the information from a failed step is included in the email. However, if step-level notification is not enabled, the information shown between <HEADER_CONTENT> and </HEADER_CONTENT> is displayed.

To access step level error handling options, click the » link in the upper right corner of the step page.

A default email layout at the step level is provided as shown in the following image.

• Select the error handling options as desired according to the description included at the workflow level.
• Enter one or more email addresses for persons to be notified in the event of an error.
  • Any recipients entered here are in addition to those defined at the workflow level.
    • Separate multiple recipients with a semi-colon (user1@twbs.com;user2@twbs.com).
• Define the email Content.
  • A default email layout at the workflow level is provided as shown in the image above. A default email layout at the workflow level is provided as shown in the image above. It should be adequate for most installations.
    • Items in < … > are selected from the “Add Tags” drop-down list. This allows you to create your own message layout if you prefer.

The table below shows how the combinations of settings at the step level affect processing. Remember that these options are also based on the settings at the workflow level.

(EEH = Enable Error Handling, EN = Enable Notification, Y = checked, N = unchecked)

Here are sample emails using the standard formats provided

The information from error handling can also be used in Decisions. The two key values are for “Step Status.” The values are True (no error) and False (error encountered). The only thing to remember is to define the values as Boolean rather than Alphanumeric in the decision expression.

It might also be possible to use the contents of the Step Message, however it would likely need to pass through a VBScript step to parse out a specific value before the decision.
