Customer Exits
Important Note: Since Release 4.6A, SAP has provided a new enhancement technique in the form of Business Add-Ins. Among others, this enhancement technique has the advantage of being based on a multi-level system landscape (SAP, country versions, IS solutions, partner, customer, and so on) instead of a two-level landscape (SAP, customer) as with the customer exits. You can create definitions and implementations of Business Add-Ins at any level of the system landscape.
To make enhancements of the SAP standard more uniform, you can migrate customer exits to Business Add-Ins.
