Further Notes

Enhancements - as opposed to modifications - are not influenced by a release upgrade because they are not part of the original SAP programs, rather, they exist in an area reserved for customers.

Each enhancement has its own documentation. You can access this documentation by clicking on Display SAP Doc. in the enhancement transaction.

Newly created user-defined fields are not automatically displayed in the information system. To display these fields in the information system, execute the report program RCNCT001. The procedure is decribed in the program documentation.
