What is the role of a user exit in SAP substitution?

1. Create new records.

2. Modify existing implementations.

3. Provide hooks for custom logic.

4. Define required fields only.

The correct answer is: Provide hooks for custom logic.

The role of a user exit in SAP substitution is to provide hooks for custom logic. User exits are essentially predefined points in the SAP standard processing where developers can insert their custom code to enhance or modify the behavior of standard SAP processes. This is particularly useful during substitution, where standard logic may need to be adjusted or expanded to fit specific business requirements. By using a user exit, organizations can implement business rules or specific calculations that are unique to their operations without modifying the standard SAP code directly. This approach supports the flexibility required in business processes while maintaining the integrity and update-ability of the standard SAP system, as the custom logic can be added or altered independently. The other choices focus on different aspects of data handling or system customization, but they do not capture the primary purpose of user exits in substitution scenarios as effectively as the correct answer. For example, creating new records and defining required fields are functionalities not tied specifically to user exits. Likewise, modifying existing implementations does not encapsulate the essence of user exits, which is fundamentally about inserting custom logic into standard processes.
