When you update a PDM generated from another model, any horizontal partitioning is preserved.
For example, the Sales CDM contains the entity Customer:
You generate the Sales PDM from the CDM, and the Customer entity is generated to the Customer table:
You partition this table using City as the criterion. The City column is excluded from the partition tables:
You modify the CDM by adding an Activity attribute to the Customer entity, and regenerate the PDM in update mode. The partitions are taken into account in the merge dialog box: The new Activity attributes are selected by default, while the City criteria columns are not selected.
