PowerDesigner comes with 2 Editions (DataArchitect and EnterpriseArchitect) and is available with different licensing models (simplified since version 16.6). Some of them were deprecated by SAP, others are still valid. This may create some confusion as to which edition, type of license and capacity is the right fit for a given project.
