Technical Implementation 
Object Types
The interface between the mySAP ERP functionality and the workflow system has been implemented using object technology. As a result, this topic contains information of a more technical nature, which is now required for a first overview.
In this context, the following object types are important:
BUS2002: Network
Position in the object repository: Project System
T024: Purchasing group
Position in the object repository: Materials management à Sales
Standard tasks
Standard tasks are single-step tasks delivered from SAP, which describe basic business processes from an organizational point of view. A single-step task always refers to an object method (technical connection to the mySAP ERP functionality) and is linked with employees, who are assigned to the relevant part of the organization.
Standard Task TS20000653:
Abbreviation: PurchOrdPS
Description: Change order network
Referenced object methods, characteristics
Object type: BUS2002
Method: DisplayPurchaseOrderChange
Characteristics: synchronous , with dialog
Process Flow
If there are changes in a network that affect ordered materials or services (quantities or dates), the affected materials are sorted according to purchasing group (in the purchase order). The event PurchaseOrderChange is then triggered for object type BUS2002 for each purchasing group.
The event BUS2002.PurchaseOrderChange is the triggering event for the standard task TS20000653. It has the following parameters:
