  Cause:
  The error is caused by an attempt to create or generate a class (or object) that has the same name as an existing class in the SAP system. This can happen if:

  There was a previous unsuccessful attempt to create or generate the class, leaving it in a partially created state.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Classes:
