• What is the cause and solution for SAP error message CNV_20700034 - Material number for conversion contains exclusively zeros ?

  The SAP error message CNV_20700034 indicates that the material number being processed for conversion consists entirely of zeros. This typically occurs during data migration or conversion processes, particularly when using SAP's data migration tools or during system upgrades.
  Cause:
  
  Invalid Material Number: The material number is expected to be a valid identifier for a material in the system. A number consisting solely of zeros is not valid and does not correspond to any existing material.
  Data Preparation Issues: The data being imported or converted may have been incorrectly prepared, leading to the generation of zero-filled material numbers.
  Mapping Errors: There may be issues in the mapping of source data to the target system, resulting in the assignment of zero values to material numbers.
  
  Solution:
  
  Check Source Data: Review the source data to ensure that material numbers are correctly populated and do not consist solely of zeros. If they are, correct the data before attempting the conversion again.
  Data Mapping: Ensure that the mapping of material numbers from the source system to the target system is correctly configured. This may involve checking transformation rules or scripts used during the migration.
  Validation Rules: Implement validation rules in the data migration process to catch and handle invalid material numbers before they cause errors.
  Consult Documentation: Refer to SAP documentation or guides related to the specific migration tool or process you are using for additional troubleshooting steps.
  Error Handling: If the error persists, consider implementing error handling in your migration process to log and skip invalid entries, allowing the process to continue with valid data.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional context on handling material number conversions.
  Data Migration Tools: Familiarize yourself with the specific data migration tools being used (e.g., SAP S/4HANA Migration Cockpit, LSMW) and their requirements for material number formats.
  Testing: Conduct thorough testing of the migration process in a development or sandbox environment before executing it in production to identify and resolve issues early.
  
  By addressing the root cause of the zero-filled material numbers and ensuring proper data preparation and mapping, you can resolve the CNV_20700034 error effectively.
