| ABAP for Key Users | This version of ABAP is designed for secure implementations of enhancements as part of enhancement points by key users provided by SAP.

Furthermore, the enhancements are implemented in methods and the stricter syntax rules for classes apply automatically. No obsolete language elements are allowed. The version ID of a program of this type is "2". The documentation for restricted ABAP is an appropriately restricted version of the full documentation. |

The version ID of program is generally transparent for developers. From a technical perspective, the version ID is in the column UCCHECK of the database table TRDIR for program attributes and is usually set by the associated tools. The statements INSERT REPORT and SYNTAX-CHECK used to edit programs either set the version implicitly or or set it explicitly using the additions VERSION and DIRECTORY ENTRY.
Note : If a program has a version ID not specified in the table above it is handled like a version that does not support any language elements.
Example
The program DEMO_ABAP_VERSIONS makes it possible to check ABAP source code using the syntax rules of the different ABAP versions.
