Summary :
This SAP Note explains the process of implementing a new data class in SAP systems and is relevant for specific databases like DB2 UDB for UNIX and Windows, Informix, Oracle, and DB2/390. It details how to create and manage a new tablespace, align it with a data class through entries in various database system-specific tables, and how to ensure the new data class is recognized by the SAP system. Key steps include defining the new data class and linking it to the newly created memory area. Be wary of potential issues such as data loss post-upgrade if modifications are not managed appropriately, particularly in SAP standard tables through transaction SE16 or ABAP/4 programming.
