Change of Attributes 
You can use this function to change the attributes of enhancements generated for service contract items (such as fuel card, tire service).
We provide enhancements for the following set types:
In the Easy Enhancement Workbench, you can create customer-specific enhancements or change the enhancements delivered by SAP.
In SAP Customer Relationship Management (SAP CRM), you use the process CHOA to change the attributes.
If you want to use customer-specific enhancements with their own attributes or change the enhancements delivered by SAP, see SAP Note 1133609.
