What is a major characteristic of enhancement points in standard SAP code?

Enhancement points in standard SAP code are specifically designed to provide targeted locations where custom enhancements can be made without modifying the original source code. This allows developers to insert their custom logic at predefined points, which helps maintain the integrity of the standard code. By utilizing enhancement points, one ensures that system updates or upgrades do not overwrite custom changes, as these enhancements occur in defined spaces that are safeguarded during system updates.

This approach fosters a clean and maintainable codebase while providing the flexibility needed to adapt standard functionalities to specific business requirements. By allowing specific spots for these custom enhancements, organizations can comply with their unique processes while still benefiting from standard SAP functionality.
