• What is the cause and solution for SAP error message CNV020 - Entries deleted ?

  The SAP error message CNV020 "Entries deleted" typically occurs in the context of data migration or conversion processes, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools. This message indicates that certain entries have been deleted from a table or a data set during the conversion process.
  Cause:
  
  Data Validation Rules: The entries may have been deleted due to failing validation checks. This can happen if the data does not meet the required criteria for the target system.
  Duplicate Entries: If the migration process detects duplicate entries that violate unique constraints, it may delete them to maintain data integrity.
  Configuration Issues: Incorrect configuration settings in the migration tool or process can lead to unintended deletions.
  Manual Deletion: Entries may have been manually deleted by users or during a previous migration step.
  Data Mapping Errors: If the mapping between source and target data is incorrect, it may lead to the deletion of entries that cannot be properly mapped.
  
  Solution:
  
  Check Logs: Review the migration logs to identify which entries were deleted and the reasons for their deletion. This can provide insights into what went wrong.
  Data Validation: Ensure that the data being migrated meets all validation rules and constraints of the target system. Clean and prepare the data accordingly.
  Configuration Review: Verify the configuration settings of the migration tool to ensure they are set up correctly. Adjust any settings that may lead to unintended deletions.
  Duplicate Handling: Implement a strategy for handling duplicates before migration, such as merging or removing duplicates in the source data.
  Testing: Conduct thorough testing in a non-production environment to identify potential issues before executing the migration in the live system.
  Backup: Always ensure that you have a backup of the data before performing any migration or conversion processes, so you can restore it if necessary.
