Enhancement Implementations 

Definition

The enhancement implementations manage the enhancements of the enhancement options, both explicitly and implicitly.

In the same way that we differentiate between enhancement options and their management in the case of enhancement spots, we also differentiate between the actual enhancement and its management in the case of enhancement implementations.

Use

An enhancement is managed by assigning one or more simple enhancement implementations to an enhancement spot of a concrete enhancement spot element definition. Conversely, every simple enhancement implementation belongs to exactly one enhancement spot. A simple enhancement implementation can have one or more enhancement implementation elements, which are assigned to the enhancement spot element definitions of the enhancement spot. A simple enhancement implementation must be assigned to at least one composite enhancement implementation:

Simple and composite enhancement implementations are Repository objects that form a tree-like structure, where the leaves and branches represent simple and composite enhancement implementations respectively.

Therefore, to implement the actual enhancement, one or more enhancement implementation elements are assigned to an enhancement spot element definition of an explicit or implicit enhancement option.

You can assign source code plug-ins, defined between ENHANCEMENT and ENDENHANCEMENT in an ABAP program, to an enhancement option defined using ENHANCEMENT-POINT. These source code plug-ins are inserted into the code unchanged if the switch is in the relevant position.

 

Enhancement implementations are processed with the Enhancement Builder tool, which is integrated in the ABAP Workbench. The Enhancement Builder’s hierarchical display of the enhancement implementations in a system shows the enhancements made in a system.

An enhancement implementation describes the enhancement of a Repository object at one or more enhancement options. An enhancement implementation element always belongs to exactly one enhancement option. However, several enhancement implementation elements can be assigned to an enhancement option. The enhancement implementation element contains the actual enhancement – for example, a source code plug-in contains the source code to be added. However, an enhancement implementation element contains no information concerning at which positions of a Repository object the enhancement options were created. Composite enhancement implementations are used for the semantic grouping of simple enhancement implementations. A composite enhancement implementation contains either one or more simple enhancement implementations and/or one or more composite enhancement implementations of the relevant type. You can use composite enhancement implementations to combine simple enhancement implementations into meaningful units.

The position of a Switch Framework switch assigned to the package of an enhancement implementation specifies whether or not an enhancement is taken into account in a system.
