Enhancement/Business Add-ins : Definition
Enhancements represent potential customer requirements that have not been developed in the standard software. Instead, the standard provides for further development of such exits at the customer site, using logic specific to the customer. Upward compatibility is assured since SAP guarantees that the call of an enhancement from the standard software and the calling interface will remain valid in future releases.
You can make enhancements to the standard using Business Add-Ins.
Business add-ins are enhancements to the standard version of the system. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values.
