This error typically occurs when you attempt to define a new rule or object in BRFplus (Business Rule Framework plus) using a key (identifier) that is already in use.
  Cause:

  Incorrect Configuration: There may be a misconfiguration in the way keys are assigned or managed within your BRFplus setup.

  Modify Existing Rule: If the existing rule with the same key is no longer needed, consider modifying or deleting it if appropriate.
  Naming Conventions: Implement a naming convention for keys to avoid future conflicts. This can help in managing keys more effectively and reducing the chances of duplication.
  Transport Requests: If you are working in a multi-system landscape, ensure that the transport requests are properly managed and that keys are not duplicated across different systems.
