  The SAP error message CNV_LTHCM_S_10079 indicates that there are duplicate records found in a cluster table for a specific component during a data migration or conversion process. This error typically arises in the context of the SAP Landscape Transformation (SLT) or during data migration activities, particularly when dealing with legacy data.
  Cause:
  The error is caused by the presence of duplicate entries in a cluster table, which violates the uniqueness constraints expected by the SAP system. Cluster tables are designed to store data in a way that allows for efficient retrieval and storage, and having duplicates can lead to inconsistencies and errors during processing.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Duplicate Records:
  
  Use SQL queries or SAP transaction codes (like SE16 or SE11) to identify the duplicate records in the specified cluster table. You can group by the relevant fields to find duplicates.
  
  
  
  Analyze the Data:
  
  Determine why duplicates exist. This could be due to data entry errors, issues during data extraction from legacy systems, or problems during previous migration processes.
  
  
  
  Remove or Consolidate Duplicates:
  
  Depending on your analysis, you may need to either delete the duplicate records or consolidate them into a single record. Ensure that you keep the necessary data and comply with business rules.
  
  
  
  Data Validation:
  
  After cleaning up the duplicates, validate the data to ensure that it meets the required standards and that no critical information has been lost.
  
  
  
  Re-run the Migration Process:
  
  Once the duplicates have been addressed, re-run the migration or conversion process to see if the error persists.
  
  
  
  Consult Documentation:
