CNV741 - Details

• The SAP error message CNV741 indicates that during a multicopy operation, duplicates were created for a specific table. This typically occurs in the context of data migration or data transformation processes, often when using tools like SAP's Data Migration Workbench or during system conversions.
  
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the source data contains duplicate entries that violate the uniqueness constraints of the target table.
  Incorrect Mapping: If the mapping of fields from the source to the target table is not correctly defined, it can lead to the creation of duplicate records.
  Data Integrity Issues: There may be underlying data integrity issues in the source data that were not addressed before the multicopy operation.
  Configuration Errors: Misconfiguration in the settings of the data migration tool or process can also lead to this error.
  
  
  Solution:
  
  Identify Duplicates: Review the source data to identify any duplicate entries that may be causing the issue.
