• Define the item type of the processDefine the item type of the process

• Define item type attributes for the processDefine item type attributes for the process

• Define lookup types and lookup codesDefine lookup types and lookup codes

• Define messagesDefine messages

• Define message attributesDefine message attributes

• Define the activities in the process as Function, Define the activities in the process as Function, Notification, or ProcessNotification, or Process

• Diagram the relationship of the activitiesDiagram the relationship of the activities


Top-Down DesignTop-Down Design

• Draw the process diagram first and then define the underlying components.

• Create new activities while drawing a process diagram.

• View activity and process activity property pages from one dialogue.

• Property page includes all tabs for base activity of the node and the usage of the individual node.

• Save a partially completed or errored process and complete or correct later.

Item Type Selector/Callback FunctionItem Type Selector/Callback Function

• The Workflow Engine can call the selector/callback function with one of three commands:

– RUN: selects the appropriate process to start

– SET_CTX: sets any item type context information needed for a function activity, prior to executing the function activity in a new database session

– TEST_CTX: determines whether a form can be launched with the current item type context information just before the Notification Detail Web page launches a reference form

Define Item Type AttributesDefine Item Type Attributes

• What should be considered an item type attribute?

– Information required by notification messages, such as the display format of a currency value

– Information required by function activities, such as values that link back to applications data like a person_ID

– Information maintained by a workflow activity, such as activities that identify who to forward information to and from in a loop construct

Document AttributesDocument Attributes

• PL/SQL document: a document representing data from the database, generated from a PL/SQL procedure.

– Ideal for use when document content varies

– For example, purchase orders with variable number of lines or sales orders with variable lines, discounts, and shipping addresses

– DM document: a document managed by an external document management system

Guided Practice Using the Quick Start Wizard

Guided Practice Using the Quick Start Wizard

1. Create a new Item Type with an internal name of “WFVACXX” where XX is the unique number assigned to your station. The display name should also include “XX” to make it easy for you to identify your Item Type. For example, the item type internal name could be “WFVAC02” and the display name “02 Vacation Proposal”. The process internal name could be “WFVAC02_PROCESS” and the display name also “02 Vacation Proposal”.

Hint: Use menu option File -> Quick Start Wizard

Guided Practice Drawing Transitions

Guided Practice Drawing Transitions

2. In the Process Diagram,

a. The process diagram is automatically created with Start and End nodes. The diagram automatically opens.

b. Select the Start node and draw a transition to the End node by holding down your right mouse button and dragging your mouse from the Start node to the End node. Let go of the right mouse button.

c. Close the Process Diagram window.
