Absolutely, you’ve got a good understanding of the different SAP offerings related to Enterprise Resource Planning (ERP). Here’s a breakdown of each:

1. SAP ERP (no longer actively sold):

• This refers to the older generation of SAP’s ERP system, traditionally deployed on-premise meaning it runs on a company’s own servers and hardware.
• It offered a wide range of functionalities but could be complex and expensive to implement and maintain.
• SAP is no longer actively selling new licenses for this system, but they still support existing customers.

2. SAP S/4HANA:

• This is the current flagship on-premise ERP system from SAP.
• It’s built on a modern, in-memory database technology called HANA, which offers significant performance improvements compared to the older SAP ERP system.
• SAP S/4HANA provides a core set of functionalities across various business areas like financials, supply chain, manufacturing, and customer relationships.

3. SAP S/4HANA Cloud:

• This is the cloud-based version of SAP S/4HANA.
• It offers the same core functionalities as the on-premise version but with a subscription-based pricing model and eliminates the need for companies to manage their own hardware.
• SAP S/4HANA Cloud is a good option for businesses seeking scalability, flexibility, and reduced IT burden.

4. SAP Business One:

• This is a separate ERP system designed specifically for small and medium-sized businesses (SMBs).
• It offers a more streamlined and affordable solution compared to SAP S/4HANA, focusing on core functionalities like financials, accounting, sales, and inventory management.

5. SAP Business ByDesign (discontinued):

• This was a cloud-based ERP system offered by SAP targeted towards mid-sized businesses.
• It positioned itself as a more user-friendly and pre-configured solution compared to the broader functionalities of SAP S/4HANA.
• SAP discontinued Business ByDesign in 2020, focusing their cloud efforts on SAP S/4HANA Cloud.
