• What is the cause and solution for SAP error message CNV_20700063 - New material number = Space; original material number = &1 ?

  The SAP error message CNV_20700063 indicates that there is an issue with the material number during a data migration or conversion process. Specifically, the error states that the new material number is being set to a space (blank), while the original material number is provided as &1, which is a placeholder for the actual material number.
  Cause:
  
  Blank Material Number: The primary cause of this error is that the system is attempting to assign a new material number that is blank or consists only of spaces. This can happen during data migration when the mapping of old material numbers to new ones is not correctly defined or when the source data has missing values.
  Data Quality Issues: The source data may have inconsistencies or missing entries, leading to the generation of a blank material number.
  Configuration Issues: There may be issues in the configuration of the migration tool or the mapping logic that leads to the generation of invalid material numbers.
  
  Solution:
  
  Check Source Data: Review the source data for the material numbers to ensure that there are no blank entries. Ensure that all required fields are populated correctly.
  Mapping Configuration: Verify the mapping configuration in the migration tool. Ensure that the logic for generating new material numbers is correctly defined and that it handles cases where the original material number is blank.
  Data Cleansing: If the source data contains blanks, consider cleansing the data before migration. This may involve filling in missing material numbers or removing entries that do not have valid identifiers.
  Error Handling: Implement error handling in the migration process to catch and log instances where a blank material number is generated, allowing for further investigation and correction.
  Testing: Conduct thorough testing of the migration process with a subset of data to identify and resolve any issues before performing a full migration.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to data migration and the specific error message for any patches or updates that may address the issue.
  Migration Tools: Familiarize yourself with the specific migration tools being used (e.g., SAP S/4HANA Migration Cockpit, LSMW) and their documentation for best practices and troubleshooting tips.
  Material Master Data: Understand the structure and requirements of material master data in SAP to ensure compliance during migration.
  
  By addressing the root cause of the blank material number and ensuring that the data is clean and correctly mapped, you can resolve the error CNV_20700063 effectively.
