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
