The data is imported into the BPM. CDM data items are
imported as elementary data and all other objects are imported as structured
data. If you import an object that has the same name, code, and type as an
existing data object in the BPM, the existing data object is reused, unless
it already has a definition object. In this case, the new data is
automatically renamed and linked to the selected object in the source
model.
When an entity, a table or a class object is imported as a data object, their
data items, columns or attributes are automatically imported as sub-data and
linked to their parent structured data.
Note: A PDM reference between two tables is imported as a parent/child
relationship between the two imported data. Foreign key column objects are
not imported because they are created by the PDM reference between
tables.
