• The SAP error message CNV_20110039 typically occurs during the data migration process, particularly when using the SAP Conversion Tools for migrating data from legacy systems to SAP S/4HANA. This specific error indicates that there is a mismatch in the expected structure of the data being processed.

  Incorrect data preparation or extraction from the legacy system.
  Issues in the mapping of data fields
