Schema File

The core schema file stores all the core table and functional object definitions. You should never modify or customize the core schema file.

The custom schema file works in combination with the core schema file to store the tables and functional objects that are available for migration, where the core schema file contains the application core schema tables and functional objects while the custom schema file contains the customized (customer-specific) schema tables and functional objects. Furthermore, the custom schema file overrides the core schema file, so if both files contain details for the same table, the table details in the custom schema file will override the table details in the core schema file. All of the tables and functional objects listed in the two files are displayed in the Select Tables/Functional Objects page of the Migration Tool.

If a table or functional object that is listed in the core schema or custom schema file does not appear in the Select Tables/Functional Objects page, this may mean the objects have been hidden via the Manage Migration Objects List. See Manage Migration Object List .
