• What is the cause and solution for SAP error message CNV_10020778 - &1 data includes for non-transparent field evaluation have been generated ?

  The SAP error message CNV_10020778 typically relates to issues encountered during data migration or conversion processes, particularly when dealing with non-transparent fields in the context of SAP's data conversion tools. This error indicates that the data being processed includes non-transparent fields, which are fields that do not have a direct mapping to a database table or structure.
  Cause:
  
  Non-Transparent Fields: The error arises when the data being processed includes fields that are not directly mappable to the target structure. Non-transparent fields can include calculated fields, fields from views, or fields that are derived from other data sources.
  Data Structure Mismatch: There may be a mismatch between the source and target data structures, especially if the target structure does not support the non-transparent fields present in the source data.
  Conversion Logic: The conversion logic may not be correctly handling the non-transparent fields, leading to issues during the data migration process.
  
  Solution:
  
  Review Data Mapping: Check the mapping of fields between the source and target systems. Ensure that all non-transparent fields are accounted for and that there is a valid mapping or transformation logic in place.
  Adjust Conversion Logic: Modify the data conversion logic to handle non-transparent fields appropriately. This may involve creating additional transformation rules or using custom logic to derive the necessary values.
  Exclude Non-Transparent Fields: If non-transparent fields are not required in the target system, consider excluding them from the migration process. This can simplify the data conversion and avoid the error.
  Consult Documentation: Refer to SAP documentation or notes related to the specific data migration tool you are using (e.g., SAP S/4HANA Migration Cockpit, SAP Data Services) for guidance on handling non-transparent fields.
  Testing: After making adjustments, perform thorough testing to ensure that the data migration process completes successfully without errors.
