Understanding Database Data Sources

The process finds the data class for each table or GT object in Object Librarian (F9860.SICLDF). Based on the environment that is being configured and the data class for the object, the data source name is fetched from F98511. If a record is not found, it looks for a record for the data class where environment name is DEFAULT (to determine whether it should be mapped to a shared data source). If a record is not found, no mapping is created and the table is effectively mapped to the default data source. If a record is found and that record is set as the default mapping data source (F98511.SPDFLTMAP), a mapping with object name DEFAULT is created; otherwise the actual object name is used. Mappings are not created for tables in the Planner and Internal data classes.
