Structure Enhancements in SAP Release 6.20
Since Release 3.0, customers have been able to make changes to SAP's ABAP Dictionary structures and tables using Customizing includes or appends. However, these changes can cause problems in programs with an active Unicode Check. For example, if a purely character-type structure is enhanced, it can lose its character-type nature and hence its Fragment View is changed.
For Release 6.20, it has therefore been made possible to classify Dictionary structures and tables, so that problems resulting from structure enhancements can be easily recognized and dealt with. This classification is used in the ABAP program check to indicate all parts of the source code that will cause problems with structure enhancements - that is, where structure enhancements will cause a syntax error or change program behavior. The Dictionary categories and their effect in ABAP programs are described in the chapter Structure Enhancements.
