Understanding Data Classes

The data class is at the center of automatic OCM generation. It categorizes the type of data stored in data sources and tables, for example, in the Business Data data source the data class is B while in the System data source the data class is S. If you want to split business data into multiple data sources, you need to create a new data class, add a data source to the data source template for that data class (so Installation Planner prompts for the data source) and assign tables and GT objects to that data class. OCM will be created based on this information. You should do these steps before creating your plan.
