Importing Technical Components
For each business function we have defined which individual parts of the enhancement packages you have to implement in your system landscape in order to be able to use the content of the business function.
New features in the enhancement packages build on the underlying SAP product instances. The enhancement packages are delivered by means of new versions of individual components of your SAP product instances.
Therefore, you only import a specific part of the delivery scope of an enhancement package into your system landscape. The specific individual technical components and contents that you need to use a business function is fixed and described in the documentation.
The individual enhancement packages build on one another, and therefore all enhancement packages are numbered according to when they appear. This means that you can also use the business functions of earlier versions.
Special installation tools are available for installing the enhancement packaages and these simplify the import considerably.
For installation purposes, the technical components and contents are summarized in the technical usage. Each business function is assigned to a technical usage, and this means that you select the components and contents required for a business function by selecting the technical usage for the installation.
The following technical components and contents contain new developments and enhancements that are available for a business function.
Software component versions of the ABAP-based system
Dependent on the required business function, instead of an entire product (for example, SAP ERP), you only implement that software component version in your existing installation that you need for the required business function, for example, EA-APPL 604 or EA-HR 604.
You should always import the most current version of an enhancement package so that, for example, you simultaneously import any corrections or further developments in further business functions for this area.
Example
For SAP ERP 6.0, you do not want to use the business functions for Human Capital Management. In this case, the ECC software component versions SAP_HR and EA-HR remain at level 6.0.
For your SAP ERP 6.0, you do want to use abusiness functions that was developed with enhancement package 2 for the Learning Solution area. In this case, you import the most up-to-date versions of the technical usage, even if you are only interested in one business function from enhancement package 2.
Software component versions for Java-based applications
Portal content
A business function can cover new or enhanced portal roles. Therefore, new versions of the business packages are available for the enhancement packages:
The version of an enhanced business package covers the following portal roles:
Portal roles in the version that was available for the previous full release (for example, SAP ERP 6.0)
Changed portal roles that are used in a business function. In addition to new iViews, the new version of a portal role can also cover iViews that were already part of the portal role of the full release.
Business Intelligence content (BI content)
In your BI system, new or changed objects as of the enhancement packages are stored in own InfoAreas. In addition, the documentation of the individual objects contains information about the enhancement package from which the objects are available and for which business function.
SAP NetWeaver Exchange Infrastructure content (XI content) and Enterprise Services
As part of the enhancement packages you receive further enterprise services. The implementations of these enterprise services are in the software component versions of your ABAP-based system. In the XI system, these Enterprise Services are grouped in own software components and namespaces for the enhancement packages. For information about these enterprise services, see the documentation of the business function and the related release notes.

Correlation between business functions, technical usages, and technical components using the example of SAP ERP business functions
It may be the case that for some business functions, you need further technical components in addition to the content of the technical usage, for example, special SAP NetWeaver components or third-party products. This information is provided in the description of the business function.
When you import a new enhancement package or upgrade to a higher full release, the business functions that you have already activated and the related settings in your ABAP-based system remain. After the installation, the business functions that you previously activated are activated automatically.
For information about the technical components required for a business function, see the documentation. For more information, see Business Function Documentation and the Master Guide for the enhancement packages.
