This typically occurs when you are attempting to create a new package or modify an existing one, and the prefix you have chosen conflicts with an existing package in the SAP system.
  Cause:
  
  Prefix Conflict: The prefix you are trying to use for your package is already assigned to another package in the SAP system.

  If the prefix is already in use, you will need to select a different, unique prefix for your package. Ensure that the new prefix adheres to SAP's naming conventions.
  
  
  
  Consult Naming Guidelines:
