  The SAP error message IUUC_MAIN025 indicates that there is an issue with the mass transfer process in the SAP Landscape Transformation (SLT) replication setup. Specifically, it means that the mass transfer process is trying to add a table that is already included in the mass transfer process.
  Cause:
  The error typically occurs due to one of the following reasons:
  
  Duplicate Table Entries: The table you are trying to add to the mass transfer process is already included in the configuration.
