pp108 : Using the Custom Error

Using the Custom Error
This topic describes the procedure to use a custom error, which is specified for a sub-process, within a main process.

Before you begin this task:
The custom error for a sub-process has to be created and mapped to the Description and the Error Code of the Exception event in the main process.

  1. Select a starting point and click (Business Process Model) to open an existing business process model.
  2. Double-click the Exception event. The Exception Event Properties - Exception pane appears.
  3. Click the General tab; type the same Description that you used while creating the Custom Error.
  4. Click the Error details tab; type the same Error Code (Process Error) that you used while creating the Custom Error.

Example of Mapping a Custom Error

The business process modeled below uses the business process model 'Get Employee details' (refer to Creating a Custom Error) as a sub-process.

"Notify Application Service" is a task and you have to create it by creating an XForm. In the 'Get Employee details' sub-process, the 'First name' of the employee is returned if it exists; else an exception (As per the example in Creating a Custom Error, 101: First name not filled) is thrown. You can handle the exception using the Exception event. You could also define more exceptions for the sub-process.

The Properties - Exception Event pane for this example is shown below.
