ISS Approval (Order) Workflow
ISS Approval (Order) workflow, shown in the following figure, validates approval rules and creates approval items if necessary.
It is triggered when the user selects the Generate Approvals menu item on the Order Header applet menu. This menu item raises the ApproveItem Signal, which calls this workflow.

Workflow Description
This workflow does the following:
Validate. Calls the Validate method of the Data Validation Manager Business Service, which validates the Order according to the Rule Sets that are defined. For more information, see Validate Method.
Exception Found. If the validation service returns a null, then the workflow ends.
Approval Bus Service. If it returns a non-null value, then the workflow calls the CreateNewApprovalTasks method of the ISS Approval Bus Service, which creates a new approval task for the Order. For more information, see CreateNewApprovalTasks Method.
Refresh Applet. Calls the Refresh Business Component method of the SIS OM PMT Service Business Service, which refreshes the Order, so the approval items appear in the approvals view.
