This error indicates that there is a mapping issue with asset numbers between company codes (CoCd) during the migration process.
  Cause:
  The error message CNV_20200_CHECK318 suggests that there is a conflict in the mapping of asset numbers between different company codes. Specifically, it indicates that an asset in one company code (CoCd &1, AssetNo &2) is being mapped to a different asset in another company code (CoCd &3, AssetNo &4). This can happen due to:

  Check Asset Mapping: Review the mapping of assets between the company codes involved. Ensure that each asset number is unique within its respective company code.
  Correct Duplicate Entries: If you find duplicate asset numbers across company codes, you may need to either rename or consolidate these assets to ensure that each asset number is unique.
  Review Migration Configuration: Verify the configuration settings in the migration tool to ensure that the mapping is set up correctly. Make adjustments as necessary.
  Data Cleansing: Perform data cleansing on the source data to eliminate any inconsistencies or duplicates before attempting the migration again.
