Budget Approval With/Without Workflow
Use
The budget control system (BCS) supports a budget approval procedure, in other words, a processor can enter a request for budget in the system which can only be approved by a superior.
You can control the approval procedure using a workflow connection. Budget requests and budget approvals are distributed by the mail system automatically. You can specify whether the approval procedure should be controlled using workflow when creating an entry document.
Prerequisites
You do this in the Customizing of Funds Management, under Workflow ® Role Definition ® Role Definition: Preposted Budget in the Budget Control System.
You define this in the Customizing of Funds Management, under Budget Control System (BCS) ® BCS Budgeting ® Budget Entry Documents ® Define Entry Document Type.
Features
SAP delivers both workflow templates WS12300025 and WS12300026 which you can use to activate the settings of the workflow-supported approval procedure.
The two workflow templates are different in that WS12300026 allows you to change the budget request if it is rejected. The rejected budget entry document can be used here as a template for creating a new request.
The functions of the generic object service are available in the budgeting workbench: You open the
Object Service Toolbox by selecting the pushbutton 
(Services for Object) on the title line of the BWB. Now you can display an overview of all budget entry documents that undergo an approval procedure. If the budget to be approved is not processed by a workflow, the person responsible for the budget can call up the entry document to be approved using the object service.
