Unit 18: Work Item Attachments 
Use
The superior is to have the opportunity to add an attachment to their work item for checking the notification of absence. This attachment is a document (any SAPscript or PC document), which is then made available to all subsequent recipients in the workflow. The superior can use this to give a full explanation for a rejection.
An attachment can be added to a workflow before the workflow is actually executed in the Business Workplace.
To create an attachment after the workflow has been executed, you have to change the definition of the associated standard task.
To enable the superior to create an attachment after the notification of absence has been checked, you must set the Confirm end of processing flag for the task Check notification of absence. This property means that the agent has to confirm the end of processing of the work item explicitly. The agent can also add an attachment before this confirmation.
For further information about using documents in workflows, refer to
Document Processing in the SAP Business Workflow documentation.Procedure
You start the Workflow Builder and open your workflow definition in Change mode. Proceed as described in

You go to the screen Standard task: Display.
Concluding step definition
The workflow definition is checked, saved, and, provided it does not contain any errors, activated. The system displays a message if problems are encountered during the test.
Result
Execution of the work item for the step Check notification of absence must be confirmed expressly. This enables you to create an attachment after the request has been approved or rejected.

You can also create attachments while a work item is being executed. An example of this is provided in the demo workflows.
