  The SAP error message CNV_MBT_46380 indicates that there are duplicate entries in a specific table during a data migration or conversion process. This error typically arises in the context of SAP's Migration Cockpit or during data transfer activities where the system expects unique entries but finds duplicates.

  Solution:
  
  Data Cleansing: Review the source data for duplicates. Use data cleansing tools or SQL queries to identify and remove duplicate entries before migration.
  Check Mapping: Ensure that the mapping of fields from the source to the target system is correct. Make sure that the keys used for identifying unique records are properly defined.
  Adjust Migration Settings: If applicable, check the settings in the migration tool to see if there are options to handle duplicates (e.g., skip, merge, or overwrite).
  Log Analysis: Review the logs generated during the migration process to identify the specific entries causing the issue. This can help in pinpointing the exact records that are duplicates.
  Testing: Before performing a full migration, conduct a test migration with a smaller dataset to identify and resolve any issues related to duplicates.
