Enhancements to the Standard
Enhancements represent potential customer requirements that have not been implemented in the standard software. The standard software enables the 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.

As of release 7.0 of SAP NetWeaver Application Server ABAP (SAP NetWeaver 7.0), a new enhancement concept exists in the ABAP Workbench, the Enhancement Framework, which helps to integrate various concepts for the modification and enhancement of development objects, and which is intended to gradually replace the previous concepts.
