Case

Your organization can use case functionality to manage a variety of business processes that are not otherwise supported by the product.

CAUTION:
The case management functionality is legacy functionality that is not recommended for future use. It has been replaced by Process Flow or an implementation may create their own business object driven maintenance object to introduce support for business processes not otherwise supported by the product. The functionality remains in the product for upgrade purposes.
Note: Your implementation controls how your cases behave. Since virtually all aspects of case functionality are controlled by your implementation, you can use it to handle a myriad of business requirements. Refer to Defining Case Options for the details.
