task types to be used for Approve Requests. Ensure that all the authorizations required for the

workflows are maintained.

2. Make sure that the required SAP Notes are installed.

3. Ensure that you have activated the Task Gateway Service and the UI5 service.

Configuration

Configuring a Task and Decisions

Enter and define a task and those decision options from your workflow task that you want to display

in the Approve Requests application.

Follow the steps below in the back-end system where you maintain your workflow template.

1. In Customizing for SAP NetWeaver, choose Gateway Service Enablement Content Workflow Settings

Maintain Task Names and Decision Options .

2. Fill in the Step Name table as described below and save your entries:

■ Workflow ID: Enter the ID of your workflow template, for example, WS30000015.

■ Step ID: Enter the task step from your workflow template.

■ Icon MIME Repository Path: Leave this field blank.

■ Step Description: Enter the task name.

This name appears as the heading of the detail screen in the Approve Requests application.

NOTE

This step is only relevant if you are implementing the Approve Requests application for your

SAP Business Workflow.

3. Select the entry in the Step Name table and choose Decision Keys in the navigation panel.

4. Add and define your decision options in the Decision Keys table as described below and save your

entries:

■ Key: Enter the decision key.

Decision keys are numeric and sequential and correspond to the position of decision options

in the Workflow Builder. Enter the first decision option with key 1, the second decision option

with key 2, and so on.

■ Icon Mime Repository Path: Leave this field blank.

■ Decision Text: Define the name of the decision option.

This name is displayed on the application screen as a button label. The proposed length of the

to the device screen.

■ Comment On: If you want to make it mandatory for the user to add a comment when executing

a decision, select this checkbox.

● Select POSITIVE for the approve type decision option.

The decision option is displayed as a green pushbutton on the detail screen of the

application.

● Select NEGATIVE for the reject type decision option.

The decision option is displayed as a red pushbutton on the detail screen of the application.

● Leave the field empty for multiple decision options.

The decision options are displayed in a gray drop-down list on the detail screen of the

application.
