Enhancement Options 

Definition

Enhancement options are positions in Repository objects where enhancements can be made. These options are either explicitly defined (by the developer) or exist implicitly. Explicit enhancement options are generally defined in a central initial system. Enhancements are made in follow-on systems.

Use

Explicit enhancement options can currently be defined by:

·        Explicitly flagging source code points or sections in ABAP programs. For an enhancement, these can be enhanced or replaced by source code plug-ins.

·        Including Business Add-Ins (BAdIs) in ABAP programs. These programs are then enhanced by object plug-ins with predefined interfaces.

Explicit enhancement options are managed by enhancement spots and enhanced by enhancement implementations.

Currently, implicit enhancement options are:

·        Specific options in ABAP programs – such as the end of the program – which can be enhanced by source code plug-ins.

·        Parameter interfaces of function modules, which can be enhanced with parameters.

·        Attributes and parameter interfaces of global classes, which can be enhanced with attributes or parameters.

Implicit enhancement options always exist and do not require enhancement spots. They are also enhanced by enhancement implementations.
