SAP Enterprise Modeling

Sorry for the delayed response. Here's how it ligns up:

SAP Enterprise Modeling: Business Architect (for SAP), IT Architect, BI Modeler

SAP Enterprise Designer: Business Designer (for SAP)

The Business Server comes with the licenses above.

SAP Business Process Optimizer: Business Optimizer, Business Simulator

For the ARIS Business Server, do we need a different license for it or we can use the licenses provided for SAP Enterprise modeling and SAP enterprise designer?

The structure of the licenses that provided to us is as the following:

5 SAP Business Designer by SW AG Licenses

1 SAP Enterprise Modeling by SW AG License

1 SAP Business Publisher by SW AG License

Is the license for ARIS Business Server missing? or we have different licenses structure for ARIS products provided by SAP?

SAP Enterprise Mod. and Des. come with a license for the Business Server. So, you don't need to buy a separate license.
