In enhancements you can use SAP information objects or information objects of other basic Basis contexts by:

• linking to SAP information objects or information objects of other basic Basis contexts

• creating enhancements to information objects and modifying these enhancements to meet your requirements

The following diagram shows how you can use SAP structures.

To reuse standard SAP structures unchanged in your enhancement, either link to it (I.a) or include it (I.b). If a subsequent enhancement release is based on a more recent SAP release, this kind of reuse automatically uses the most recent SAP structure version.

If you only want to use a SAP structure in your enhancements in modified form, you must first create an enhancement version of the structure. This can then be modified and if necessary referenced with a link (II.a) or an include (II.b).

Enhancing SAP objects has the following advantages compared to creating information objects:

• It saves the effort required to create the structure and topics. This is particularly significant when only minor modifications should be made to the standard system.
• Standard R/3 links remain valid. These links can thus be used unchanged in an enhancement.
• Links to the info objects remain valid and the enhancement object now appears in the enhancement context in all places that link to the SAP object on which it is based.
