• What is the cause and solution for SAP error message CNV_20900066 - &1: hidden field &2 does not contain a value ?

  The SAP error message CNV_20900066 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that a hidden field (field &2) is expected to contain a value, but it is currently empty or not populated.

  Missing Data: The field that is supposed to contain a value is not populated in the source data. This could be due to data extraction issues or incomplete data in the source system.
  Mapping Issues: There may be a problem with the mapping of fields between the source and target systems, leading to the hidden field not being filled correctly.
  Configuration Issues: The configuration of the migration tool or the data model may not be set up correctly, causing certain fields to be overlooked or not filled.
  Data Validation Rules: The data being migrated may not meet the validation rules set in the target system, leading to the rejection of the data for that field.
  
  Solution:
  
  Check Source Data: Review the source data to ensure that the hidden field (field &2) is populated correctly. If it is missing, you may need to update the source data or adjust the extraction process to include it.

  Adjust Migration Settings: If applicable, adjust the settings in the migration tool to ensure that all necessary fields are included in the migration process.
  Data Cleansing: Perform data cleansing on the source data to ensure that all required fields are populated and meet the validation criteria of the target system.
