• What is the cause and solution for SAP error message CNV_DMC_HC103 - Duplicate entries of table &1 exist in Settings for Latency Check ?

  The SAP error message CNV_DMC_HC103 indicates that there are duplicate entries in a specific table related to the settings for latency checks in the Data Migration Cockpit (DMC). This error typically arises during data migration processes when the system detects that the same entry has been defined more than once, which can lead to inconsistencies and errors in data processing.
  Cause:
  The primary cause of this error is the presence of duplicate entries in the configuration settings for latency checks. This can happen due to:
  
  Manual entry errors where the same configuration is added multiple times.
  Issues during data import or migration where the same settings are inadvertently duplicated.
  Inconsistent data management practices leading to repeated entries.
  
  Solution:
  To resolve the CNV_DMC_HC103 error, you can follow these steps:
  
  
  Identify Duplicate Entries:
  
  Access the relevant configuration table in the SAP system where the latency check settings are stored. This is typically done through transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser).
  Query the table to find duplicate entries. You can use SQL queries or built-in tools to identify duplicates based on key fields.
  
  
  
  Remove or Correct Duplicates:
  
  Once you have identified the duplicates, you can either delete the redundant entries or correct them if they are not supposed to be duplicates.
  Ensure that you keep the necessary entries that are required for the latency checks to function correctly.
  
  
  
  Validate Changes:
  
  After making changes, validate the configuration to ensure that the duplicates have been removed and that the settings are functioning as expected.
  You may want to run a test migration or check the latency settings to confirm that the error no longer occurs.
  
  
  
  Documentation and Best Practices:
  
  Document the changes made to the configuration to maintain a record for future reference.
  Implement best practices for data entry and configuration management to prevent similar issues from occurring in the future.
