Understanding Creating OCM Mappings

You can create OCM mappings (TBLE, GT, BSFN, UBE) for new or copied environments. OCM mappings for a new or copied environment are created by setting up mappings for tables and GTs, and then configuring BSFN and UBE mappings.

TBLE, GT When Creating New Environments

The software finds the data class for each table or GT object in the Object Librarian Master table (F9860). Based on the environment and data class for the object, the data source name is fetched from the data sources by the Environment table (F98511). If a record is not found, the software looks for a record for the data classes where environment name is DEFAULT (a shared data source). If that data source is the default mapping, 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.

TBLE, GT When Copying Environments

The software looks at each *PUBLIC OCM record for TBLE and GT objects for the environment being copied. It then fetches the data class for the object from Object Librarian. It then looks in F98511 for the data source in the new environment for that data class. If the data source is different from that in OCM, it changes the OCM mapping to point to the new data source.

BSFN, UBE OCM Mappings

The OCM generation algorithm for UBEs and BSFNs is identical, but the output depends on whether the default mapping is LOCAL or an enterprise server.
