This error indicates that there is an attempt to create a package label list with a key that already exists in the system.
  Cause:
  The primary cause of this error is that the system is trying to create a new package label list using a key (usually a unique identifier) that is already in use. This can happen due to:

  To resolve the RMSL288 error, you can take the following steps:
  
  
  Check Existing Package Label Lists:
