The SAP error message "CL_DFPS_COMP_EWM020 BO class name & already exists. Please enter a new BO class name" typically occurs in the context of Business Object (BO) class creation or modification within the SAP system, particularly in the Extended Warehouse Management (EWM) module. This error indicates that the Business Object class name you are trying to use is already in use or has been defined previously in the system.
Cause:
- Duplicate Class Name: The primary cause of this error is that the Business Object class name you are trying to create or modify already exists in the system. SAP does not allow duplicate names for Business Object classes to maintain data integrity and avoid confusion.
- Namespace Issues: If you are working in a specific namespace, there might be conflicts with existing classes in that namespace.
- Transport Requests: If you are working in a development environment and have not yet transported changes to the quality or production environment, there may be discrepancies in class names across different environments.
Solution:
- Choose a Unique Name: The simplest solution is to select a different, unique name for your Business Object class. Ensure that the new name adheres to any naming conventions your organization may have.
- Check Existing Classes: Before creating a new Business Object class, check the existing classes in the system to see if the name you want to use is already taken. You can do this by navigating to the relevant transaction codes or using the Object Navigator (SE80).
- Namespace Considerations: If you are working within a specific namespace, ensure that the name you are trying to use does not conflict with existing classes in that namespace.
- Transport Management: If you suspect that the issue is related to transport requests, ensure that all relevant changes have been transported correctly and that you are working with the latest version of the objects in your environment.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
