There are various scenarios for which SAP Business Workflow can be used for production orders:
If the standard tasks and workflow templates that are supplied do not meet your requirements, you can enhance them or create new tasks. If you want to enhance the tasks supplied by SAP, copy them and change the copies as required.
When you have created tasks yourself and need new attributes, methods or events for an object type, you should create a subtype for this object type. You can change these subtypes any way you like. If necessary, make the subtype the delegation type of the original object type.
You will find more information about the scenarios in the component BC - Basis by choosing Business Management -> SAP Business Workflow -> Workflow Scenarios in Applications -> PP - Production Planning and control.
