You can export BPM data objects as data items, entities, tables or classes in other PowerDesigner models. The target model must be open in the workspace, and only data objects which are not already linked to any external model objects are available for export.
If you export a data object that has the same name and code as an existing object in the target model, the data will be linked to the existing object.
You cannot export a data object more than once. If you want to re-export a data object, you must first delete the link to the external object.
A class attribute or a table column cannot be shared, but sub-data objects can be shared by several data object parents. When you export an elementary or undefined sub-data object as an attribute in the OOM or as a column in the PDM, the link between the sub-data object and the definition object is not saved in the Definition box of its property sheet.
